  Lecture Notes 3
The purpose of this lecture is to help you to understand conceptually the meanings of measures of locations (i.e., mean, median, and mode) and measures of variability (i.e., range, variance, standard deviation, and coefficient of variation).
For example, to compute the arithmetic mean of a sample of numbers, such as 19, 20, 21, 23, 18, 25, and 26, first sum the numbers: (19+20+21+23+18+25+26) = 152, and then calculate the sample mean by dividing this total (152) by the number of observations (7), which gives a mean of 21.7 or about 22.
Generally, the median provides a better measure of location than the mean when there are some extremely large or small observations (i.e., when the data are skewed to the right or to the left).

Napier termed this technique location arithmetic from the way in which the locations of the counters on the board represented and computed numbers.
Location arithmetic was an elegant insight into the simplicity of binary arithmetic, but remained a curiosity probably because it was never clear that the effort to convert numbers in and out of binary form was worth the trouble.
Location arithmetic in particular foreshadowed the ease of and power of mechanizing binary arithmetic, but was never fully appreciated.

 php-deluxe.net - description Location arithmetic
To represent a number as a location numeral, express it as a sum of powers of two and replace the powers by the alphabets.
Notice that since each alphabet is twice the value of the previous alphabet, you can replace two occurrences of the same alphabet with one of the next alphabet without changing the value of the number.
If on the other hand a location numeral has repeated alphabets, it is the extended form of the number.

The decimal arithmetic instructions are used to adjust the results of a previous binary arithmetic operation to produce a valid packed or unpacked decimal result, or to adjust the inputs to a subsequent binary arithmetic operation so the operation will produce a valid packed or unpacked decimal result.
When the mnemonic ends with "ps", the source operand can be a 128-bit memory location or a SSE register, the destination operand must be a SSE register and the operation is performed on packed four single precision values, for each pair of the corresponding data elements separately, the result is stored in the destination register.
Arithmetic operations on double precision values are: "addpd", "addsd", "subpd", "subsd", "mulpd", "mulsd", "divpd", "divsd", "sqrtpd", "sqrtsd", "maxpd", "maxsd", "minpd", "minsd", and they are analoguous to arithmetic operations on single precision values described in previous section.

 Doing It Fast, fixed point arithmetic techniques and fast 3d transforms
Floating point arithmetic is easy to use and it comes closer to working the way we expect arithmetic to work than any other kind of arithmetic we can use in programs.
Fixed point arithmetic uses ordinary integer operations to do arithmetic with numbers that have both a whole part and a fractional part.
When we want to use fixed point arithmetic in a program we have to decide what format to use and how to implement it within the programming language we are using.

Second are the locations of the two numbers to be operated upon; these locations are often entered into the ladder diagram as get instructions, which resemble examine instructions and which tell the program where to find the numbers in memory.
The third and final part of an arithmetic ladder rung is the output location; it's usually entered as an address assigned to the actual arithmetic instruction (+, -, x, or /), which resembles a relay coil instruction.
Another group of arithmetic instructions are the compare instructions, which determine if one number is less than, equal to, or greater than another number.

The dyadic arithmetic operations include per-band addition, subtraction, multiplication and division between two source images to produce a destination image.
For example, for image addition the value at location 0,0 in one source image is added to location 0,0 of the second source image and the result is stored in location 0,0 of the destination image.

 Parallel filter check using an arithmetic memory location patent invention
Memory locations are packed with multiple sub-variables for comparison to sub-variables generated, for example, at runtime.
At the time of comparing sub-variables, the result of the modified twos complement arithmetic is added to a variable, and the carryout bit of each sub-variable of the resulting variable is evaluated to determine results of the comparisons.
The carryout bit is also used to separate the sub-variables in the memory location to prevent a sub-variable from affecting an adjacent sub-variable.

What is needed is a way to use the social security number with a hashing function which would determine a unique location for each name and really only use an array of records which is slightly longer than 500 records.
However, if after inserting the first element into the location, subsequent hashing has resulted in the same location and rehashing has been used to place the element in another position, taking out the first element causes problems.
When searching, if the element is not found at the first locations, the rehashing procedure is used to determine the next position to check until the search is either successful or not.

When using the arithmetic mean to calculate the mean of a population one makes the assumption that the arithmetic mean is a valid estimate of the central location of a distribution, which is not always true.
Adjusting the number needed to treat for the baseline risk of the patient implies, as underlined by Cook and Sackett,6 that the relative risk reduction is constant for all levels of disease severity.
Nevertheless, the arithmetic mean is only the most probable value of a population (provided the variable is normally distributed) and is not the value observed in every individual.

 Pointer Arithmetic
Arbitrary pointer casting allows you to access any memory location and do anything you want at that location, regardless of whether you can access that memory location or whether the data is valid at that memory location.
Fortunately, our goal is simply to understand pointer arithmetic which is adding integers to pointers and subtracting pointers.
It's said that a good programmer understands pointers very well, while an average programmer finds anything with more than one pointer difficult to manage (e.g., a pointer to a pointer to an int is seen as difficult).

Locations can be created and assigned to variables using the by operator, which returns the location given by the x and y coordinates.
The wonderful feature of these numbers is that you can do arithmetic with them as if they were any other number, and the result is always another complex number.
Locations also have some functions of their own, such as rotate and flip.

 Location Sets
When the position of a location within a block is entirely unknown, we set the location set stride to one.
Although we recognize simple pointer increments, which are commonly used to address array elements, to determine the location set strides, we do not attempt to evaluate more complex pointer arithmetic.
Instead, for each memory address input to an arithmetic expression, we add to the result a location set with the same base object but with the stride set to one.
