The OpenType spec (in the section on `"normalization" of OpenType Font Variations `_) defines the required method for converting floating point values to fixed-point. In particular it specifies the following rounding strategy: for fractional values of 0.5 and higher, take the next higher integer; for other fractional values, truncate. This function rounds the floating-point value according to this strategy in preparation for conversion to fixed-point. Args: value (float): The input floating-point value. Returns float: The rounded value. ?)intmathfloorrrrr rsrcCs ||}t|||kr|S|Sr)abs)v toleranceroundZroundedrrr r,srcCs8|dkrtd|dkrtS|dkr(|Stjt||dS)Nrz#Rounding tolerance must be positiver rr) ValueErrorr functoolspartialrrrrr r0sr)r factorreturncCs|sdSt|||}d|}||}||}t|t|krPttt|Sd}||}||}t|t|kr|||ksJtt|D]}||||krqq|d}||ksJd||}||S)a"Round to nearest multiple of factor and return shortest decimal representation. This chooses the float that is closer to a multiple of the given factor while having the shortest decimal representation (the least number of fractional decimal digits).

Args: value (value): The value to be rounded and serialized. factor (float): The value which the result is a close multiple of.
