Description
int gmp_cmp(GMPintstring $num1
, GMPintstring $num2
)
Parameters
-
num1
-
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
-
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).
Return Values
Returns a positive value if a > b
, zero if
a = b
and a negative value if a <
b
.
Examples
Example #1 gmp_cmp example
<?php
$cmp1 = gmp_cmp("1234", "1000"); // greater than
$cmp2 = gmp_cmp("1000", "1234"); // less than
$cmp3 = gmp_cmp("1234", "1234"); // equal to
echo "$cmp1 $cmp2 $cmp3\n";
?>
The above example will output:
