f32-to-number
xod/bits/f32-to-number
Converts 32-bit IEEE-754 encoded floating point number presented as four bytes to a number. A result of the conversion will be in range 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.
