2014-01-29auto merge of #11672 : bjz/rust/remove-times, r=brsonbors-43/+0
`Times::times` was always a second-class loop because it did not support the `break` and `continue` operations. Its playful appeal (which I liked) was then lost after `do` was disabled for closures. It's time to let this one go.

2014-01-20Improve std::num::pow implementationBrendan Zabarauskas-42/+30
The implementation has been made more succinct and no longer requires Clone. The coverage of the associated unit test has also been increased to check more combinations of bases, exponents, and expected results.

appropriate use Zero and One have precise definitions in mathematics. Documentation has been added to describe the appropriate uses for these traits and the laws that they should satisfy.

2014-01-18Replace old pow_with_uint with the new pow funcFlavio Percoco-43/+7
There was an old and barely used implementation of pow, which expected both parameters to be uint and required more traits to be implemented. Since a new implementation for `pow` landed, I'm proposing to remove this old impl in favor of the new one. The benchmark shows that the new implementation is faster than the one being removed: test num::bench::bench_pow_function ..bench: 9429 ns/iter (+/- 2055) test num::bench::bench_pow_with_uint_function ...bench: 28476 ns/iter (+/- 2202)

2014-01-18auto merge of #11622 : bjz/rust/simplify-primitive-trait, r=brsonbors-84/+31
As part of #10387, this removes the `Primitive::{bits, bytes, is_signed}` methods and removes the trait's operator trait constraints for the reasons outlined below: - The `Primitive::{bits, bytes}` associated functions were originally added to reflect the existing `BITS` and `BYTES`statics included in the numeric modules. These statics are only exist as a workaround for Rust's lack of CTFE, and should be deprecated in the future in favor of using the `std::mem::size_of` function (see #11621). - `Primitive::is_signed` seems to be of little utility and does not seem to be used anywhere in the Rust compiler or libraries. It is also rather ugly to call due to the `Option<Self>` workaround for #8888. - The operator trait constraints are already covered by the `Num` trait.

2014-01-17Add a generic power functionFlavio Percoco-40/+68
The patch adds a `pow` function for types implementing `One`, `Mul` and `Clone` trait. The patch also renames f32 and f64 pow into powf in order to still have a way to easily have float powers. It uses llvms intrinsics. The pow implementation for all num types uses the exponentiation by square. Fixes bug #11499

2014-01-13Remove RealExtBrendan Zabarauskas-49/+1
These functions are of little utility outside a small subset of use cases. If people need them for their own projects then they can use their own bindings for libm (which aren't hard to make).
2014-01-09auto merge of #11412 : bjz/rust/num-cleanups, r=alexcrichtonbors-272/+232
The methods contained in `std::num::{Algebraic, Trigonometric, Exponential, Hyperbolic}` have now been moved into `std::num::Real`. This is part of an ongoing effort to simplify `std::num` (see issue #10387). `std::num::RealExt` has also been removed from the prelude because it is not a commonly used trait. r? @alexcrichton
2014-01-09Remove ApproxEq and assert_approx_eq!Brendan Zabarauskas-106/+23
This trait seems to stray too far from the mandate of a standard library as implementations may vary between use cases.

2013-12-04auto merge of #10803 : vmx/rust/integer-decode, r=cmrbors-0/+60
The `integer_decode()` function decodes a float (f32/f64) into integers containing the mantissa, exponent and sign. It's needed for `rationalize()` implementation of #9838. The code got ported from ABCL [1]. [1] http://abcl.org/trac/browser/trunk/abcl/src/org/armedbear/lisp/FloatFunctions.java?rev=14465#L94 I got the permission to use this code for Rust from Peter Graves (the ABCL copyright holder) . If there's any further IP clearance needed, let me know.

This function had type &[u8] -> ~str, i.e. it allocates a string internally, even though the non-allocating version that take &[u8] -> &str and ~[u8] -> ~str are all that is necessary in most circumstances.
