Function std.math.exponential.powmod
Computes the value of a positive integer x
, raised to the power n
, modulo m
.
Unqual!(Largest!(F,H)) powmod(F, G, H)
(
F x,
G n,
H m
)
if (isUnsigned!F && isUnsigned!G && isUnsigned!H);
Parameters
Name | Description |
---|---|
x | base |
n | exponent |
m | modulus |
Returns
x
to the power n
, modulo m
.
The return type is the largest of x
's and m
's type.
The function requires that all values have unsigned types.
Example
writeln(powmod(1U, 10U, 3U)); // 1
writeln(powmod(3U, 2U, 6U)); // 3
writeln(powmod(5U, 5U, 15U)); // 5
writeln(powmod(2U, 3U, 5U)); // 3
writeln(powmod(2U, 4U, 5U)); // 1
writeln(powmod(2U, 5U, 5U)); // 2
