2024-08-28std: update `std.builtin.Type` fields to follow naming conventionsmlugg
The compiler actually doesn't need any functional changes for this: Sema does reification based on the tag indices of `std.builtin.Type` already! So, no zig1.wasm update is necessary. This change is necessary to disallow name clashes between fields and decls on a type, which is a prerequisite of #9938.
2024-03-21Update frexp.zig (#19370)Sean
1. Entirely rewrote frexp with generics, reducing the implementation to a single function and enabling parameters of types f80 and f16 2. Expanded upon the tests, making them more descriptive and comprehensive, and automatically generating the test bodies for each floating point type 3. Added a doctest for frexp
2023-06-24all: migrate code to new cast builtin syntaxmlugg
Most of this migration was performed automatically with `zig fmt`. There were a few exceptions which I had to manually fix: * `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten * `@truncate`'s fixup is incorrect for vectors * Test cases are not formatted, and their error locations change
2021-10-05add support for f128 `@mulAdd`Andrew Kelley
std: add f128 implementations of fma, frexp, and ilogb. Expose `fmal` in zig's freestanding libc. This makes `@mulAdd` work correctly for f128. Fixes a CI regression from yesterday, where I added a usage of f128 `@mulAdd` into the self-hosted compiler.
2021-08-24remove redundant license headers from zig standard libraryAndrew Kelley
We already have a LICENSE file that covers the Zig Standard Library. We no longer need to remind everyone that the license is MIT in every single file. Previously this was introduced to clarify the situation for a fork of Zig that made Zig's LICENSE file harder to find, and replaced it with their own license that required annual payments to their company. However that fork now appears to be dead. So there is no need to reinforce the copyright notice in every single file.

2020-11-05std: Implement more useful approxEq semanticsLemonBoy
Comparisons with absolute epsilons are usually useful when comparing numbers to zero, for non-zero numbers it's advised to switch to relative epsilons instead to obtain meaningful results (check [1] for more details). The new API introduces approxEqAbs and approxEqRel, where the former aliases and deprecated the old `approxEq`, allowing the user to pick the right tool for the job. The documentation is meant to guide the user in the choice of the correct alternative. [1] https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/

2019-12-10Replace @typeOf with @TypeOf in all zig sourceRobin Voetter
This change was mostly made with `zig fmt` and this also modified some whitespace. Note that in some files, `zig fmt` produced incorrect code, so the change was made manually.
