Change literal representation to not truncate Also shuffles around the organization of numeric literals and types, separating by int/uint/float instead of machine-vs-non-machine types. This simplifies some code. Closes #974 Closes #1252 2011-12-07 20:06:12 +00:00

Fix overflowing_literals lint for large f32s Float literals need to be parsed as the correct type so they can be rounded correctly. 2017-07-19 02:22:45 +00:00
Update tests to remove old numeric constants Part of #68490. Care has been taken to leave the old consts where appropriate, for testing backcompat regressions, module shadowing, etc. The intrinsics docs were accidentally referring to some methods on f64 as std::f64, which I changed due to being contrary with how we normally disambiguate the shadow module from the primitive. In one other place I changed std::u8 to std::ops since it was just testing path handling in macros. For places which have legitimate uses of the old consts, deprecated attributes have been optimistically inserted. Although currently unnecessary, they exist to emphasize to any future deprecation effort the necessity of these specific symbols and prevent them from being accidentally removed. 2020-10-24 23:21:40 +00:00			`assert_eq!(-3.40282356e+38_f32, f32::MIN);`
