Description

Support for arbitrary precision mathematics in PHP.

Zend_Crypt_Math_BigInteger_Bcmath is a wrapper across the PHP BCMath extension.

Methods

add
jump to class

add(
          string $left_operand, string $right_operand
          )
        
        :
        string

Adds two arbitrary precision numbers

Arguments

$left_operand: string
$right_operand: string

Output

string

Details

visibility: public
final: false
static: false

binaryToInteger
jump to class

binaryToInteger(
           $operand
          )
        
        :

Arguments

$operand

Details

          string $left_operand, string $right_operand
          )
        
        :
        int

Compare two big integers and returns result as an integer where 0 means both are identical, 1 that left_operand is larger, or -1 that right_operand is larger.

Arguments

$left_operand: string
$right_operand: string

Output

int

Details

        :
        string|null

Divide two big integers and return result or NULL if the denominator is zero.
