Methods
Adds two arbitrary precision numbers
add(string $left_operand, string $right_operand) : string
inherited_from |
\Zend_Crypt_Math_BigInteger_Interface::add() |
Parameters
$left_operand
string
$right_operand
string
Returns
string
binaryToInteger()
binaryToInteger(string $operand) : string
inherited_from |
\Zend_Crypt_Math_BigInteger_Interface::binaryToInteger() |
Parameters
$operand
string
Returns
string
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.
compare(string $left_operand, string $right_operand) : integer
inherited_from |
\Zend_Crypt_Math_BigInteger_Interface::compare() |
Parameters
$left_operand
string
$right_operand
string
Returns
integer
Divide two big integers and return result or NULL if the denominator
is zero.
divide(string $left_operand, string $right_operand) : string | null
inherited_from |
\Zend_Crypt_Math_BigInteger_Interface::divide() |
Parameters
$left_operand
string
$right_operand
string
Returns
string
null
hexToDecimal()
hexToDecimal(string $operand) : string
inherited_from |
\Zend_Crypt_Math_BigInteger_Interface::hexToDecimal() |
Parameters
$operand
string
Returns
string
Initialise a big integer into an extension specific type. This is not
applicable to BCMath.
init(string $operand, integer $base = 10
) : string
inherited_from |
\Zend_Crypt_Math_BigInteger_Interface::init() |
Parameters
$operand
string
$base

Returns
string
integerToBinary()
integerToBinary(string $operand) : string
inherited_from |
\Zend_Crypt_Math_BigInteger_Interface::integerToBinary() |
Parameters
$operand
string
Returns
string
Get modulus of an arbitrary precision number
modulus(string $left_operand, string $modulus) : string
inherited_from |
\Zend_Crypt_Math_BigInteger_Interface::modulus() |
Parameters
$left_operand
string
$modulus
string
Returns
string
Multiply two arbitrary precision numbers

inherited_from |
\Zend_Crypt_Math_BigInteger_Interface::multiply() |
Parameters
$left_operand
string
$right_operand
string
Returns
string
Raise an arbitrary precision number to another
pow(string $left_operand, string $right_operand) : string
inherited_from |
\Zend_Crypt_Math_BigInteger_Interface::pow() |
Parameters
$left_operand
string
$right_operand
string
Returns
string
Raise an arbitrary precision number to another, reduced by a specified
modulus
powmod(string $left_operand, string $right_operand, string $modulus) : string
inherited_from |
\Zend_Crypt_Math_BigInteger_Interface::powmod() |
Parameters
$left_operand
string
$right_operand
string
$modulus
string
Returns
string
Get the square root of an arbitrary precision number
sqrt(string $operand) : string
inherited_from |
