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.

37: Add Inv and Pow traits. r=cuviper a=clarcharr

This is not a breaking change, and closes #34 and #38.

This doesn't add any impls for the other `num` crates, just floats with `std` enabled. The trait has to be added before those other crates can be updated.

32: Implement CoreFloat trait r=cuviper a=vks

This is a subset of the `Float` trait, but works with `no_std`.
Some code was simplified by using `CoreFloat`.
