You are right, i guess i wasn't clear enough.

In 5.5f, f is the float literal, i am trying to write generic code.
Say i changed the type to f64(double), or f128 by just changing a line.

typedef f128 scalar;
// or in D
alias f128 scalar;

So each cast above will be like f128(5.5f)...
What have i gained by increasing precision to 64 or 128 bit here?

Clear enough? :)

Thanks!
