Ip i float rand & 0xff / 10.0f
WebNov 16, 2012 · @GlennMaynard: If you were dividing by (RAND_MAX+1ULL) (presumably a power of 2), you'd just be scaling the FP exponent. Some rounding is actually necessary: if you want to generate uniform float value over [0..1], but still have a chance to generate every representable float, you need multiple integer values to round to the same final float for …
