GLSL pow function?

Question

I have this:

    float xExponential = pow(xPingPong, 5);

And is not working, claiming:

ERROR: 0:53: No matching overload for call to function 'pow'

Am I doin' something wrong? Developing for iOS with OpenGL ES 2.0.

Can you try this ?

float xExponential = pow(xPingPong, 5.0);

Reason is that 5 is a integer and 5.0 is a float (and the pow function is not defined for pow(float,int). There is no automatically typecast in GLSL, but you could force the correct type by float xExponential = pow(xPingPong, float(5)); - not that it makes sense in this example. – Mortennobel May 06 '12 at 16:27

Your code is fine just syntax error

Write upto decimal digit

 float xExponential = pow(xPingPong, 5.0);

or

 float xExponential = pow(xPingPong, 5.);
