longToBinary()

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

rand()

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
