gmp_div_q — Divide numbers
$num1, GMP |int |string $num2, int $rounding_mode = GMP_ROUND_ZERO ): GMP
Divides num1 by num2 and
returns the integer result.
num1The number being divided.
A GMP object, an int ,
or a string that can be interpreted as a number following the same logic
as if the string was used in gmp_init() with automatic
base detection (i.e. when base is equal to 0).
num2
The number that num1 is being divided by.
A GMP object, an int ,
or a string that can be interpreted as a number following the same logic
as if the string was used in gmp_init() with automatic
base detection (i.e. when base is equal to 0).
rounding_mode
The result rounding is defined by the
rounding_mode, which can have the following
values:
GMP_ROUND_ZERO : The result is truncated
towards 0.
GMP_ROUND_PLUSINF : The result is
rounded towards +infinity.
GMP_ROUND_MINUSINF : The result is
rounded towards -infinity.
A GMP object, an int ,
or a string that can be interpreted as a number following the same logic
as if the string was used in gmp_init() with automatic
base detection (i.e. when base is equal to 0).
A GMP object.
Example #1 gmp_div_q() example
<?php
$div1 = gmp_div_q("100", "5");
echo gmp_strval($div1) . "\n";
$div2 = gmp_div_q("1", "3");
echo gmp_strval($div2) . "\n";
$div3 = gmp_div_q("1", "3", GMP_ROUND_PLUSINF);
echo gmp_strval($div3) . "\n";
$div4 = gmp_div_q("-1", "4", GMP_ROUND_PLUSINF);
echo gmp_strval($div4) . "\n";
$div5 = gmp_div_q("-1", "4", GMP_ROUND_MINUSINF);
echo gmp_strval($div5) . "\n";
?>The above example will output:
20 0 1 0 -1
Note:
This function can also be called as gmp_div() .
