Floating-point numbers are used for decimal and exponential values. For example, We must add the suffix f or F at the end of a float value. This is because the compiler interprets decimal values without the suffix as double. Consider this code. WebThese lines of code snap a float dx to nearest snap: if (snap <= 1f) dx = Mathf.Floor (dx) + (Mathf.Round ( (dx - Mathf.Floor (dx)) * (1f / snap)) * snap); else dx = Mathf.Round (dx / snap) * snap; So if snap is 0.5, value gets rounded to nearest 0.5 value (1.37 goes to 1.5), if it is 0.02, value is rounded to nearest 0.02 ( (1.37 goes to 1.38)). mallards mating season
