number-to-f32
xod/bits/number-to-f32
Converts a number to 32-bit IEEE-754 encoded floating point number presented as four bytes. An input for the the conversion should be between -3.4E+38 to 3.4E+38 with an accuracy of 7 digits. It means, a float number greater than seven digits in length will be inaccurate and lose a fractional part.
