gmp_powm
Raise number into power with modulo
Description
GMP gmp_powm(GMPintstring $num, GMPintstring $exponent, GMPintstring $modulus)
Parameters
-
num
-
The base number.
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).
-
exponent
-
The positive power to raise the num.
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).
-
modulus
-
The modulo.
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
The new (raised) number, as a GMP number.
Examples
