WebIn (a), the 16-bit IEEE 754 float16 floating-point format is shown (corresponding to (−1) í µí± × 2 í µí°¸−15 × 1.í µí± 2 for normalized values), with 1 sign bit, 5 exponent bits and 10... WebJan 20, 2024 · So a floating point 0.25 converted to an 8-bit unsigned integer may be 63 or 64, even though 0.25 * 255 = 63.75, and is closer to 64. Signed. For signed, normalized integers, the conversion is slightly more complicated. Signed integers in OpenGL are represented as Two's complement numbers.
