Member Function Documentation

Auth_OpenID_MathLibrary.longToBinary

(

$

long

)

Given a long integer, returns the number converted to a binary string. This function accepts long integer values of arbitrary magnitude and uses the local large-number math library when available.

Parameters:

integer

$long The long number (can be a normal PHP integer or a number created by one of the available long number libraries)

Returns:

string $binary The binary version of $long

Definition at line 45 of file BigMath.php.

Auth_OpenID_MathLibrary.binaryToLong

(

$

str

)

Given a binary string, returns the binary string converted to a long number.

Parameters:

string

$binary The binary version of a long number, probably as a result of calling longToBinary

Returns:

integer $long The long number equivalent of the binary string $str

Auth_OpenID_MathLibrary.rand

(

$

stop

)

Returns a random number in the specified range. This function accepts $start, $stop, and $step values of arbitrary magnitude and will utilize the local large-number math library when available.

Parameters:

	integer	$start The start of the range, or the minimum random number to return
	integer	$stop The end of the range, or the maximum random number to return
	integer	$step The step size, such that $result - ($step * N) = $start for some N

Returns:

integer $result The resulting randomly-generated number
