IParseable<float> and IParseable<double> would fail when parsing a decimal point number due to incorrect NumberStyles parameter. E.g. IParseable<double>.TryParse would fail as opposed to IParseable<double>.Parse because the former explicitly states to use NumberStyles.Integer

LGTM. feel free to send mail to Steve/tactics. The key point being it's only the preview methods affected (I would have snipped out the diff for the non preview methods even though it's a no-op, but it's not important.) |

Customer Impact
Customers using the new generic math preview feature will not be able to use
IParseable<float>,IParseable<double>orIParseable<Half>and have it work for anything except strings containing integers.They would need to fallback to the parse methods exposed by
INumber<T>that take aNumberStylesinstead.Testing
Additional tests were duplicated and updated to explicitly cover the generic math scenario.
Risk
Low. This is a small fix for a preview API that requires explicit opt-in to consume.
