Question

I have a variable in Python containing a floating point number (e.g. num = 24654.123), and I\'d like to determine the number\'s precision and scale values (in t

Answer 1

If you need to check the number of corresponding digits (of a and b)

def prec_check(a, b):

  a = str(a)
  b = str(b)
  do = bool(True)
  n = 0

  while do == True:

    if a and b and a[n] == a[b]:
      n += 1

    else:
      do = false

    return n

Note that this doesn't work with the "Decimal" module.
