# bccomp

bccomp -- Compare two arbitrary precision numbers.

## Description

`int bccomp`(string left operand, string right operand, int [scale]);

Compares the `left operand` to the `right operand` and returns the result as an integer. The optional `scale` parameter is used to set the number of digits after the decimal place which will be used in the comparion. The return value is 0 if the two operands are equal. If the `left operand` is larger than the `right operand` the return value is +1 and if the `left operand` is less than the `right operand` the return value is -1.
