Actually this is pretty simple, head over gl.h to see how GLfloat is defined, in fact it is a good old float.

or any other function from math.h library :(

try this, maybe forget about r1 :

GLfloat f1 =0.3f;

float r1;

double r2;

r1 = abs((float)f1);

r2 = abs((double)f1);

GLfloat f1 =0.3f;

float r1;

double r2;

r1 = abs((float)f1);

r2 = abs((double)f1);
