2020-02-12T19:20:56+00:00

Rollup merge of #68266 - Stromberg90:patch-2, r=Dylan-DPC

2020-01-16T06:28:07+00:00

Changed docs for f32 and f64.

Update f64.rs

Use 3.6 instead of 3.5 in float fract() documentation

2020-01-15T18:46:44+00:00

It is not self-explanatory whether the fract() function inverts the fractional part of negative numbers. Co-Authored-By: Mateusz Mikuła

Remove negative number check from float sqrt

2020-01-04T23:44:19+00:00

It hasn't been UB to pass negative numbers to sqrt since https://reviews.llvm.org/D28797 which was included in LLVM 5.

Format libstd with rustfmt

2019-11-30T02:43:27+00:00

This commit applies rustfmt with rust-lang/rust's default settings to files in src/libstd *that are not involved in any currently open PR* to minimize merge conflicts. THe list of files involved in open PRs was determined by querying GitHub's GraphQL API with this script: https://gist.github.com/dtolnay/aa9c34993dc051a4f344d1b10e4487e8 With the list of files from the script in outstanding_files, the relevant commands were: $ find src/libstd -name '*.rs' \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ rg libstd outstanding_files | xargs git checkout -- Repeating this process several months apart should get us coverage of most of the rest of libstd. To confirm no funny business: $ git checkout $THIS_COMMIT^ $ git show --pretty= --name-only $THIS_COMMIT \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ git diff $THIS_COMMIT # there should be no difference

Auto merge of #63871 - BatmanAoD:FloatFnMustUse, r=withoutboats

2019-11-09T17:02:49+00:00

Add #[must_use] to all functions 'fn(float) -> float' These are pure functions. ```rust impl f32/f64 { fn floor(self) -> Self; fn ceil(self) -> Self; fn round(self) -> Self; fn trunc(self) -> Self; fn fract(self) -> Self; fn abs(self) -> Self; fn signum(self) -> Self; fn mul_add(self, a: Self, b: Self) -> Self; fn div_euclid(self, rhs: Self) -> Self; fn rem_euclid(self, rhs: Self) -> Self; fn powi(self, n: i32) -> Self; fn powf(self, n: Self) -> Self; fn sqrt(self) -> Self; fn exp(self) -> Self; fn exp2(self) -> Self; fn ln(self) -> Self; fn log(self, base: Self) -> Self; fn log2(self) -> Self; fn log10(self) -> Self; fn abs_sub(self, other: Self) -> Self; fn cbrt(self) -> Self; fn hypot(self, other: Self) -> Self; fn sin(self) -> Self; fn cos(self) -> Self; fn tan(self) -> Self; fn asin(self) -> Self; fn acos(self) -> Self; fn atan(self) -> Self; fn atan2(self, other: Self) -> Self; fn exp_m1(self) -> Self; fn ln_1p(self) -> Self; fn sinh(self) -> Self; fn cosh(self) -> Self; fn tanh(self) -> Self; fn asinh(self) -> Self; fn acosh(self) -> Self; fn atanh(self) -> Self; fn clamp(self, min: Self, max: Self) -> Self; } ``` Part of #48926

using 2.0.log(2.0) in examples does not make it clear which is the base and number. This example makes it clear for programmers who take a glance at the example by following the calculation. It is more intuitive, and eliminates the need for executing the example in the playground.

Restore 'must_use' for 'clamp'; fix warning for tests

2019-09-05T16:22:11+00:00

Let 'clamp' be invoked without using return value; used in tests
