 Palindromic number - Wikipedia, the free encyclopedia
It is fairly straightforward to appreciate that in any base there are infinitely many palindromic numbers, since in any base the infinite sequence of numbers written (in that base) as 101, 1001, 10001, etc. (in which the nth number is a 1, followed by n zeroes, followed by a 1) consists of palindromic numbers only.
Although palindromic numbers are most often considered in the decimal system, the concept of palindromicity can be applied to the natural numbers in any numeral system.
All numbers in base 10 with one digit {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} are palindromic ones.

 3.2.4 Number Theory
The number theory group at Oklahoma State University has established a thriving program of research, including a regular seminar series featuring lectures of both a research and expository nature by the resident number theorists, as well as frequent lectures by distinguished young and senior number theorists from around the country.
Number theory is famed not just for the beauty of its theorems, but for the enormous wealth and variety of techniques involved in discovering and proving these theorems.
Our faculty is prepared to offer courses in algebraic number theory, class field theory, analytic number theory, the arithmetic of elliptic curves as well as other arithmetic algebraic varieties, p-adic analysis, automorphic and modular forms, discrete subgroups of algebraic groups, computational number theory, as well as many other subfields of number theory.

 Math Forum - Ask Dr. Math
If you have a number like 12132 in base 4, you group the digits in pairs from the right, as "01 21 32" and rewrite converting each of those 2-digit base 4 numbers to one base-16 digit, giving 19E in hexadecimal.
The base 4 number 12132 stands for the base 10 expression 1*4^4 + 2*4^3 + 1*4^2 + 3*4^1 + 2*4^0 where the "^" indicates a power or exponent.
Since 4^1 is just 4 and 4^0 is 1, this can also be written as 1*4^4 + 2*4^3 + 1*4^2 + 3*4 + 2 Now, to make the next step clearer, I'll add some parentheses to focus attention on parts of the expression.

 XML Path Language (XPath)
If the result is a number, the result will be converted to true if the number is equal to the context position and will be converted to false otherwise; if the result is not a number, then the result will be converted as if by a call to the boolean function.
NOTE: The number function should not be used for conversion of numeric data occurring in an element in an XML document unless the element is of a type that represents numeric data in a language-neutral format (which would typically be transformed into a language-specific format for presentation to a user).
In addition, the number function cannot be used unless the language-neutral format used by the element is consistent with the XPath syntax for a Number.
