PHP12 - BCMATH library of functions

For arbitrary precision mathematics PHP offers the Binary Calculator (BCMATH library of functions) which supports numbers of any size and precision, represented as strings.

    The BCMATH library includes the following functions:
  • bcadd() - Add two arbitrary precision numbers
  • bccomp() - Compare two arbitrary precision numbers
  • bcdiv() - Divide two arbitrary precision numbers
  • bcmod() - Get modulus of an arbitrary precision number
  • bcmul() - Multiply two arbitrary precision number
  • bcpow() - Raise an arbitrary precision number to another
  • bcpowmod() - Raise an arbitrary precision number to another, reduced by a specified modulus
  • bcscale() - Set default scale parameter for all bc math functions
  • bcsqrt() - Get the square root of an arbitrary precision number
  • bcsub() - Subtract one arbitrary precision number from another

This test uses 8 of the 10 (all but bcpowmod() and bcscale()) predefined functions included in the BCMATH library. This test is successful when a (correct) result is displayed in the red box(es) for each of the functions.
