math.pow

from "math" import pow

Returns x raised to the power y

Parameters

Return value

x raised to the power y, as a float.

Notes

The result is always a float, even when both x and y are integers: type(pow(2, 3)) is "float".

Out-of-domain input does not throw. A negative x with a fractional y gives NaN; x equal to 0 with a negative y gives infinity. Both print differently between compilers and platforms, so do not print them from portable code.

Example

from "math" import pow

println("pow(2, 10) =", pow(2, 10))
println("pow(2.0, 0.5) =", pow(2.0, 0.5))

// integer arguments still give a float result
println("type(pow(2, 3)) =", type(pow(2, 3)))

pow(2, 10) = 1024
pow(2.0, 0.5) = 1.41421
type(pow(2, 3)) = float
