Vinzent Steinberg 6430351e74 Use constant for 180/π in f32::to_degrees
The current `f32::to_degrees` implementation uses a division to
calculate 180/π, which causes a loss of precision. Using a constant is
still not perfect (implementing a maximally-precise algorithm would come
with a high performance cost), but improves precision with a minimal
change.

This is a backport from [`std`].

52: Refactor ToPrimitive range checks r=cuviper a=cuviper

This is a rebase and continuation of PR #28.  The primary benefit is that
floats finally check for overflow before casting to integers, avoiding
undefined behavior.  Fixes #12.

The inter-integer conversions and all of the macros for these have also been
tweaked, hopefully improving readability.  Exhaustive tests have been added for
good and bad conversions around the target MIN and MAX values.

Josh Stone a4d234c253 Further simplify float-to-int range checks
We don't actually need to compute the `trunc()` value, as long as we can
figure out the right values for the exclusive range `(MIN-1, MAX+1)` to
measure the same truncation effect.

Dan Barella 3534a89858 Don't use assert_ne!
`num` is tested against `rust 1.8.0`, which doesn't include
`assert_ne!` -- so we use a plain ol' `assert` instead.

Dan Barella f99aa0e181 Check overflow when casting floats to integers.
This change adds some new macro rules used when converting from floats
to integers. There are two macro rule variants, one for signed ints, one
for unsigned ints.

Among other things, this change specifically addresses the overflow case
documented in https://github.com/rust-num/num-traits/issues/12

41: Various improvements to FloatCore r=vks a=cuviper

- New macros simplify forwarding method implementations.
  - `Float` and `Real` use this to compact their implementations.
  - `FloatCore` now forwards `std` implementations when possible.
- `FloatCore` now requires `NumCast`, like `Float does.
- New additions to `FloatCore`:
  - Constants like `min_value()` -> `f64::MIN`
  - Rounding methods `floor`, `ceil`, `round`, `trunc`, `fract`
  - `integer_decode` matching `Float`'s
- Fix NAN sign handling in `FloatCore` (rust-num/num#312, rust-lang/rust#42425)
- Fix overflow in `FloatCore::powi` exponent negation.
- Add doctests to all `FloatCore` methods.
