WebAug 20, 2024 · If c > 1.0f, including INF, it is clamped to 1.0f. If c < 0.0f, including -INF, it is clamped to 0.0f. Convert from float scale to integer scale: c = c * (2ⁿ-1). Convert to integer. c = c + 0.5f. The decimal fraction is dropped, and the remaining floating point (integral) value is converted directly to an integer.
