fdiv — Divides two numbers, according to IEEE 754
Returns the floating point result of dividing the
num1
by the num2
.
If the num2
is zero, then one of INF
,
-INF
, or NAN
will be returned.
Note that in comparisons, NAN
will never ==
or ===
,
any value, including itself.
num1
The dividend (numerator)
num2
The divisor
The floating point result of
num1
/num2
示例 #1 Using fdiv()
<?php
var_dump(fdiv(5.7, 1.3)); // float(4.384615384615385)
var_dump(fdiv(4, 2)); // float(2)
var_dump(fdiv(1.0, 0.0)); // float(INF)
var_dump(fdiv(-1.0, 0.0)); // float(-INF)
var_dump(fdiv(0.0, 0.0)); // float(NAN)
?>
