No it would not, but you could use decimals in xml. Edit: looks like there is no float in xml.

- bedatadriven 6y agoNor are there floats in JSON! Json numbers are stored in decimal with varying lengths.
- treve 6y agoYes, but almost any standard JSON package will map a number with decimals to their internal float. While alternative parsers exists (javascript has LosslessJSON for example), they're a pain to use. Using strings for floats only has a tiny overhead, but it allows users to use standard JSON parsers and it signals a good practice. If you use JSON numbers to serialize money, you create a situation where the path with the least friction is the incorrect one.
- masklinn 6y ago> While alternative parsers exists (javascript has LosslessJSON for example), they're a pain to use. FWIW in Python that's as uncomplicated as json.loads('1.1', parse_float=decimal.Decimal) though of course it helps tremendously that `decimal` is part of the stdlib.
- faichai 6y agoNumbers in JSON are stored as strings. So as long as encoder/decoder is storing them in suitable format e.g BigDecimal no precision need be lost.
- microcolonel 6y agoThat may be technically true, but decoding sad encoding JSON without reading numbers as doubles is a special feature.
