When raising to a power of a fractional number, an incorrect subtraction occurs:

import std.stdio;

void main()
{
float x;
x=1/2;
writeln (4^^x);
writeln (4^^(1/2));
}

Your problem becomes apparent if you writeln(x). The calculation does integer division (1 goes 0 times into 2) and then assigns that to a float. What you want is x=1.0/2; and 4^^(1.0/2).
