clamp() methods added to Math and StrictMath `int clamp(long, int, int)` is somewhat different, as it accepts a `long` value and safely clamps it to an `int` range. Other overloads work with a particular type (long, float and double). Using similar approach in other cases (e.g. `float clamp(double, float, float)`) may cause accidental precision loss even if the value is within range, so I decided to avoid this.
In all cases, `max >= min` precondition should met. For double and float we additionally order `-0.0 < 0.0`, similarly to what Math.max or Double.compare do. In double and float overloads I try to keep at most one arg-check comparison on common path, so the order of checks might look unusual. For tests, I noticed that tests in java/lang/Math don't use any testing framework (even newer tests), so I somehow mimic the approach of neighbour tests. ------------- Commit messages: - Line breaks - Trailing whitespace removed - Copyright added - 8301226 Add clamp() methods to java.lang.Math and to StrictMath Changes: https://git.openjdk.org/jdk/pull/12428/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=12428&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8301226 Stats: 426 lines in 3 files changed: 425 ins; 0 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/12428.diff Fetch: git fetch https://git.openjdk.org/jdk pull/12428/head:pull/12428 PR: https://git.openjdk.org/jdk/pull/12428
