From these numbers you need to get x less than there is and y more than it is.
x = 0.001 or x = 0.0015 Y = 0.0025
numbers may be different, i.e. Fixed Round (x, 4) is not suitable, because they can be 0.0001514 and then I will get x = 0.0002, which will be more initial number.
thought to the part of Fraction or bitwise operations, but somehow I do not quite understand how it can be realized. Maybe someone did this.
Answer 1, Authority 100%
Number – number
precision – signs in fractional part
math.floor (Number * 10 ** Precision) / 10 ** Precision
- math.floor (- Number * 10 ** Precision) / 10 ** Precision
