gmp_div_q — Divide numbers
Divides num1 by num2 and
returns the integer result.
num1The number being divided.
GMP 对象、int 或 string，可以按照跟在 gmp_init() 中使用字符串并自动检测 base（即当 base 等于 0 时）相同的逻辑将其解释为数字。
num2
The number that num1 is being divided by.
GMP 对象、int 或 string，可以按照跟在 gmp_init() 中使用字符串并自动检测 base（即当 base 等于 0 时）相同的逻辑将其解释为数字。
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.

示例 #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";
?>以上示例会输出：
20 0 1 0 -1
注意:
This function can also be called as gmp_div().
