<float>^<float>: Illegal Use of Floating Point

[raysa]

Hi,

I got the error "Illegal Use of Floating Point" when
I put in a formula like:

Code: Select all

float result = 0.3^0.5;
float result = 0.3^5;
float result = 3^0.5;

I really need to do this kind of calculation but
couldn't figure out what data-type should it take
to proceed a formula in <float>^<float> form.
I've tried float, double, and long double with no success.
I'm sure there must be a way to do the trick.

Thank's in advance,
raysa

^ is a bitwise xor operator in C++, and it cannot be applied to floating point types.

If you need exponentiation, use pow(x, y).
For square roots you can use sqrt(x);

Solved that way.
Thank you, mf! Really appreciate it.
