GL_OES_single_precision#
Supported Hardware#
Series5, Series5XT, Series6, Series6XE, Series6XT
Valid APIs#
OpenGL ES 1.x
Description#
This function is basically the equivalent of the GL_OES_fixed_point, but for floating point functions. This extension doesn’t actually express anything, as these functions exist in the common profile anyway. Theoretically it could have made some sort of sense in a Common-Lite Profile (fixed point only), but this never happened in practice.
Note#
This functionality is core to OpenGL ES 2.0 and 3.0.

Example#
// Use a floating-point function
GLfloat rgbaBlendValues[4] = {0.0f, 0.0f, 0.0f, 0.0f};
glGetFloatv(GL_BLEND_COLOR, rgbaBlendValues);
