gmp_export - Export to a binary string

SYNOPSIS

       string gmp_export (GMP  $gmpnumber, integer  $word_size, integer  $options)

DESCRIPTION

	Export a GMP number to a binary string

PARAMETERS

	      o $gmpnumber
		- The GMP number being exported

	      o $word_size
		- Default value is 1. The number of bytes in each chunk of binary data. This is mainly used in conjunction with the options param-
		eter.

	      o $options
		- Default value is GMP_MSW_FIRST | GMP_NATIVE_ENDIAN.

";
	      ?>

gmp_clrbit - Clear bit

SYNOPSIS

       void gmp_clrbit (GMP  $a, int  $index)

DESCRIPTION

	Clears (sets to 0) bit $index in $a. The index starts at 0.

PARAMETERS

	      o $a
		-Either  a  GMP number resource in PHP 5.5 and earlier, a GMP object in PHP 5.6 and later, or a numeric string provided that it is
		possible to convert the latter to a number.

	      o $index
		- The index of the bit to clear. Index 0 represents the least significant bit.

RETURN VALUES

	A GMP number resource in PHP 5.5 and earlier, or a GMP object in PHP 5.6 and later.

EXAMPLES

       Example #1

	      gmp_clrbit(3) example

	      <?php
	      $a = gmp_init("0xff");
	      gmp_clrbit($a, 0); // index starts at 0, least significant bit
	      echo gmp_strval($a) . "
";
	      ?>

	      The above example will output:

	      254

NOTES

       Note

	       Unlike most of the other GMP functions, gmp_clrbit(3) must be called with a GMP resource that already exists (using gmp_init(3) for
	      example). One will not be automatically created.
