Convert base 10 int to any other base up to 16. This function will take a take two integer values. The first is the base you want to convert to, the second is the base 10
number you are converting.
The Greatest Common Denominator of two large numbers, using BCMath functions. Please read the PHP manual for BCMath requirements. It works even for those who cannot have GMP
support in their PHP distribution, for instance due to the web host policy.
An application for doing exact integer computations. Uses bcmath functions of PHP. The Euclidean Algorithm and the Sieve of Erotesthenes are implemented.
This is a port of the FFT code in NR to PHP. The size of the input array must be an integer power of two. Main website at http://www.mathewbinkley.org/fft.php
Allows manipulation and display of a fraction. Useful for displaying float/double as a fraction as opposed to a decimal number, i.e. 1/2 instead of 0.5, or a better example is
1/3 instead of 0.333333. :-)
fmtnum() takes a number and formats it for easy reading. It can convert a number to scientic notation or return it with quantifier attached. For example, you could use it to
format the number 12345678 into 1x10+7 or 12.34 M.
The code fragment (function) allows to find the scheme of all possible combinations of a given number of elements and will return the array with all combinations. Optionally
it allows to find also the combinations that dont include all elements. The examples show how to apply the code. Idea/basics of the code were taken from a nice contribution

Takes a number like 1000.000001 and rounds it to 1001, or 1000.9 and rounds it to 1001 I made this for my paginator which gets the total pages then divides by amount per page,
sometimes it returns 1.1 or 1.00001 etc, so it rounds it up for a solid number to use for the paginator
take for example, you want to have 2 significiant digits, then 3.34 => 3.3 0.003445 => 0.0034 345.45 => 340 1 => 1.0 0.02 => 0.020 3.45e-4 => 0.00034 0 =>
0.0
A simple Add, Subtract, Multiply, and Divide Calculator. This is a short example of a form, data validation, commenting, CSS, HTML, and rather neat code. Beginners may benifit
from the source code contained within.
This is a statistic class that accepts one or two unidimensional arrays of data. It returns a stat array using the getStats() method. If only one array is sent, it will return
the min,max, sum, median, average and standard deviation for this array. If two arrays are sent, in addition to these values for both arrays, a linear regression line is
computed with its correlation r and 't'test. Median correction applied on 02/26/01.
