public static int floatToIntBits(float value)
floatToIntColorback to summary
public static int floatToIntColor(float value)

Converts the color from a float ABGR encoding to an int ABGR encoding. The alpha is expanded from 0-254 in the float encoding (see intToFloatColor(int)) to 0-255, which means converting from int to float and back to int can be lossy.

public static float intBitsToFloat(int value)
intToFloatColorback to summary
public static float intToFloatColor(int value)

Encodes the ABGR int color as a float. The alpha is compressed to use only even numbers between 0-254 to avoid using bits in the NaN range (see Float#intBitsToFloat(int) javadocs). Rendering which uses colors encoded as floats should expand the 0-254 back to 0-255, else colors cannot be fully opaque.
