bcadd - Add two arbitrary precision numbers

SYNOPSIS

       string bcadd (string  $left_operand, string  $right_operand, [int  $scale])

DESCRIPTION

	Sums $left_operand and $right_operand.

PARAMETERS

	      o $left_operand
		- The left operand, as a string.

	      o $right_operand
		- The right operand, as a string.

	      o $
		scale  -This  optional	parameter  is used to set the number of digits after the decimal place in the result. You can also set the
		global default scale for all functions by using bcscale(3).

RETURN VALUES

	The sum of the two operands, as a string.

EXAMPLES

       Example #1

	      bcadd(3) example

	      <?php

	      $a = '1.234';
	      $b = '5';

	      echo bcadd($a, $b);     // 6
	      echo bcadd($a, $b, 4);  // 6.2340

	      ?>

DECHEX(3)								 1								 DECHEX(3)

dechex - Decimal to hexadecimal

SYNOPSIS

       string dechex (int  $number)

DESCRIPTION

	Returns a string containing a hexadecimal representation of the given unsigned $number argument.

	The largest number that can be converted is PHP_INT_MAX
	* 2 + 1 (or -1): on 32-bit platforms, this will be 4294967295 in decimal, which results in dechex(3) returning ffffffff.

PARAMETERS

	      o $number
		-  The	decimal  value to convert.  As PHP's integer type is signed, but dechex(3) deals with unsigned integers, negative integers
		will be treated as though they were unsigned.

RETURN VALUES

	Hexadecimal string representation of $number.

EXAMPLES

       Example #1

	      dechex(3) example

	      <?php
	      echo dechex(10) . "
";
	      echo dechex(47);
	      ?>

	      The above example will output:

	      a
	      2f

       Example #2

	      dechex(3) example with large integers

	      <?php
	      // The output below assumes a 32-bit platform.
	      // Note that the output is the same for all values.
	      echo dechex(-1)."
";
	      echo dechex(PHP_INT_MAX * 2 + 1)."
";
	      echo dechex(pow(2, 32) - 1)."
";
	      ?>

	      The above example will output:

	      ffffffff
	      ffffffff
	      ffffffff
