 Numerical Terms
Numerical terms are used in chemical names for indicating a number of identical structural units in a compound.
The use of these numerical terms for expressing identical substituents to a parent structure, and their modifications for use with "complex" substituents, is described in Rule A-2.5.
However, the multiplying prefixes "bis-", "tris-", etc., are used instead of "di-", "tri-", etc., when the use of the latter would result in a potential ambiguity; for example, tris(decyl) is used to describe three decyl substituents because tridecyl is the name for a thirteen carbon acyclic substituent.

 NIST Guide to SI Units - Rules and Style Conventions
The selection of the appropriate decimal multiple or submultiple of a unit for expressing the value of a quantity, and thus the choice of SI prefix, is governed by several factors.
It is often recommended that, for ease of understanding, prefix symbols should be chosen in such a way that numerical values are between 0.1 and 1000, and that only prefix symbols that represent the number 10 raised to a power that is a multiple of 3 should be used.
On the other hand, a numerical value equation expresses a relation among numerical values of quantities and therefore does depend on the units used to express the values of the quantities.

  HANDLE.NET FAQs
A prefix is a globally unique string, assigned by CNRI, which identifies your handle service (and your identifiers) to the Global Handle Registry, and which will be used as the first part, or "prefix", of each of the identifiers you create under that naming authority.
However, upon request, temporary prefixes may be allotted for use in evaluating and testing the handle system technology for an agreed trial period.
Prefixes issued under this license will be five digits or larger.

For example, "3W" moves the cursor to the beginning of the third word after the one where the cursor is now, while "-2W" moves the cursor to the beginning of the second word before the one in which the cursor is presently located.
If it has a numerical prefix, then the character with that ASCII value is inserted before the character under the cursor, and the cursor remains on the character it was on before (i.e., after the new character).
This form of the insert command can be used to insert some characters that cannot be inserted by typing (e.g., characters with their high bit set) and some that cannot be inserted using the second form of the insert command that we will look at shortly (e.g., the escape character).

 Units: Metric Prefixes
There is a widespread misconception that prefixes for positive powers of ten are all capitalized, leading to the use of K- for kilo- and D- for deca-.
The last letter of a prefix is often omitted if the first letter of the unit name is a vowel, causing the combination to be hard to pronounce otherwise.
However, the last letter of the prefix is not omitted if pronunciation is not a problem, as in the case of the milliampere.

If you supply no prefix argument, and the selected unit(s) can add any one of several types of terrain, then you will be asked to choose the terrain type.
The prefix argument gives the number of parts of detach; by default, the unit will be divided in half.
If, for instance, the prefix is 2, then the unit will stop moving when it reaches the first cell that is 2 or fewer cells from the destination.

 Filtering Incomplete User Input
When entering numerical data in a text window, it is best to inform the user that it is invalid as soon as an unwanted character is entered.
However, when the numerical string contains a decimal point, the comparison must be done by comparing the input string with the limit string truncated to the same number of fractional digits.
In particular, if the string being checked is a valid prefix of a floating point number, extending it with a digit yields a floating point number.
