Description

int bccomp ( string left_operand, string right_operand [, int scale])

The optional scale parameter is used to set the number of digits after the decimal place which will be used in the comparison. 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.
