OpenGL ES 2.0 Type casting
Is type casting from float to GLfloat safe? I don't care how much precision is lost or gained if it represents the same geometric shape correct enough. I don't wanna port/rewrite all the general library to make it GL compatible. If there is no issue, I am gonna use GL only in critical functions. For example, when writing draw() funciton. That is, casting will be automatic after passing the float parameters to a cube function for example. Can I do that? Is the casting safe enough?

It's absolutely safe and with no loss of precision, since float and GLfloat are exactly the same.
GLfloat merely exists for compatibility between platforms where floats may be defined differently.
In general, though, its declaration is:
typedef float GLfloat;
