    function count_fraction_length()

    var number_to_string = "123.1000";

    var length = number_to_string.length;

    var position = number_to_string.indexOf(".")+1;

    Log.Message(length-position);

It looks like better to use aqConvert.FloatToStr() method and then parse the result using regular expression:

 

import re

def decimals(yourFloat):

    converted_num = aqConvert.FloatToStr(yourFloat)
    pattern = re.compile("\.[0-9]*")	
    res = re.search(pattern, converted_num)
    if res is not None:
        res = res.group(0)
	return len(res[1:])
