2013-04-29Revert "Merge Exponential and Hyperbolic traits"Brendan Zabarauskas-3/+9
After discussions on IRC and #4819, we have decided to revert this change. This is due to the traits expressing different ideas and because hyperbolic functions are not trivially implementable from exponential functions for floating-point types.
2013-04-29Merge Exponential and Hyperbolic traitsBrendan Zabarauskas-9/+3
The Hyperbolic Functions are trivially implemented in terms of `exp`, so it's simpler to group them the Exponential trait. In the future these would have default implementations.

The `target_word_size` attribute is always available at compile time, so there is no need for a fallback.

2013-04-27Add Orderable traitBrendan Zabarauskas-2/+152
This is a temporary trait until we have default methods. We don't want to encumber all implementors of Ord by requiring them to implement these functions, but at the same time we want to be able to take advantage of the speed of the specific numeric functions (like the `fmin` and `fmax` intrinsics).
2013-04-26Combine PrimitiveInt, Int, and Uint traits into one single traitBrendan Zabarauskas-22/+6
Having three traits for primitive ints/uints seemed rather excessive. If users wish to specify between them they can simply combine Int with either the Signed and Unsigned traits. For example: fn foo<T: Int + Signed>() { … }

2013-04-25Use borrowed pointers for Integer methodsBrendan Zabarauskas-71/+71
This brings them in line with the quot and rem traits, and is be better for large Integer types like BigInt and BigUint because they don't need to be copied unnecessarily.
2013-04-25Rename Natural to IntegerBrendan Zabarauskas-3/+3
'Natural' normally means 'positive integer' in mathematics. It is therefore strange to implement it on signed integer types. 'Integer' is probably a better choice.

This adds the following methods to ints and uints: - div - modulo - div_mod - quot_rem - gcd - lcm - divisible_by - is_even - is_odd I have not implemented Natural for BigInt and BigUInt because they're a little over my head.

`uint::range_step` or `int::range_step` causes overflow or underflow as following. code: ```rust fn main() { for uint::range_step(3, 0, -2) |n| { println(fmt!("%u", n)); } } ``` output: ``` 3 1 18446744073709551615 18446744073709551613 ... ``` This commit fixes this behavior as follows. ``` 3 1 ```
2013-04-08auto merge of #5787 : alexcrichton/rust/less-mut-fields, r=catamorphismbors-47/+33
This removes some of the easier instances of mutable fields where the explicit self can just become `&mut self` along with removing some unsafe blocks which aren't necessary any more now that purity is gone. Most of #4568 is done, except for [one case](https://github.com/alexcrichton/rust/blob/less-mut-fields/src/libcore/vec.rs#L1754) where it looks like it has to do with it being a `const` vector. Removing the unsafe block yields: ``` /Users/alex/code/rust2/src/libcore/vec.rs:1755:12: 1755:16 error: illegal borrow unless pure: creating immutable alias to const vec content /Users/alex/code/rust2/src/libcore/vec.rs:1755 for self.each |e| { ^~~~ /Users/alex/code/rust2/src/libcore/vec.rs:1757:8: 1757:9 note: impure due to access to impure function /Users/alex/code/rust2/src/libcore/vec.rs:1757 } ^ error: aborting due to previous error ``` I also didn't delve too much into removing mutable fields with `Cell` or `transmute` and friends.
