BC Math Binary Calculator

Introduction

The Binary Calculator can be used to calculate with numbers of any size and precision up to 2147483647-1 decimals, in string format. The Binary Calculator is more precise than the float calculation of PHP.

Syntax

• string bcadd ( string $left_operand , string $right_operand [, int $scale = 0 ] )
• int bccomp ( string $left_operand , string $right_operand [, int $scale = 0 ] )
• string bcdiv ( string $left_operand , string $right_operand [, int $scale = 0 ] )
• string bcmod ( string $left_operand , string $modulus )
• string bcmul ( string $left_operand , string $right_operand [, int $scale = 0 ] )
• string bcpowmod ( string $left_operand , string $right_operand , string $modulus [, int $scale = 0 ] )
• bool bcscale ( int $scale )
• string bcsqrt ( string $operand [, int $scale = 0 ] )
• string bcsub ( string $left_operand , string $right_operand [, int $scale = 0 ] )

Parameters

Remarks

For all BC functions, if the scale parameter is not set, it defaults to 0, which will make all operations integer operations.
