Re: weird behavior for machine epsilon in float, double and real

This is the same code of yours, a bit refactored:

import std.stdio: writefln;

template Tuple(T...) { alias T Tuple; }

void computeEpsilon(T)() {
    T ep = 1;
    T n = 1;

    while ((ep + n) != n)
        ep /= 2;

    writefln("%.30f type: %s", ep, typeid(T));
}

void main() {
    foreach (T; Tuple!(float, double, real))
        computeEpsilon!(T)();
}

Bye,
