move `test-float-parse` tool into `src/tools` dir

2025-06-03T08:05:51+00:00

Obviously `test-float-parse` is a tool like any other in `src/tools`. Signed-off-by: onur-ozkan

float: Add `f16` parsing and printing

2025-05-18T16:43:13+00:00

Use the existing Lemire (decimal -> float) and Dragon / Grisu algorithms (float -> decimal) to add support for `f16`. This allows updating the implementation for `Display` to the expected behavior for `Display` (currently it prints the a hex bitwise representation), matching other floats, and adds a `FromStr` implementation. In order to avoid crashes when compiling with Cranelift or on targets where f16 is not well supported, a fallback is used if `cfg(target_has_reliable_f16)` is not true.

Rollup merge of #138034 - thaliaarchi:use-prelude-size-of, r=tgross35

2025-03-07T09:12:44+00:00

library: Use `size_of` from the prelude instead of imported Use `std::mem::{size_of, size_of_val, align_of, align_of_val}` from the prelude instead of importing or qualifying them. These functions were added to all preludes in Rust 1.80. try-job: test-various try-job: x86_64-gnu try-job: x86_64-msvc-1

dec2flt: Refactor the fast path

2025-03-02T09:35:42+00:00

This is just a bit of code cleanup to make use of returning early.

dec2flt: Refactor float traits

2025-03-02T09:35:42+00:00

A lot of the magic constants can be turned into expressions. This reduces some code duplication. Additionally, add traits to make these operations fully generic. This will make it easier to support `f16` and `f128`.

dec2flt: Rename fields to be consistent with documented notation

dec2flt: Rename `Number` to `Decimal`

2025-03-02T07:08:01+00:00

The previous commit renamed `Decimal` to `DecimalSeq`. Now, rename the type that represents a decimal floating point number to be `Decimal`. Additionally, add some tests for internal behavior.

dec2flt: Rename `Decimal` to `DecimalSeq`

2025-03-02T07:08:00+00:00

This module currently contains two decimal types, `Decimal` and `Number`. These names don't provide a whole lot of insight into what exactly they are, and `Number` is actually the one that is more like an expected `Decimal` type. In accordance with this, rename the existing `Decimal` to `DecimalSeq`. This highlights that it contains a sequence of decimal digits, rather than representing a base-10 floating point (decimal) number. Additionally, add some tests to validate internal behavior.
