Please consider this proposal to add a method `unsignedMultiplyHigh(long,long)` to each of `java.lang.Math` and `java.lang.StrictMath`.
Brian Burkhalter has updated the pull request incrementally with one additional commit since the last revision:
8188044: Add @see links between multiplyHigh() and unsignedMultiplyHigh().
src/java.base/share/classes/java/lang/Math.java line 1211:
1209: long z1 = t >>> 32; 1210: 1211: return x1 * y1 + z1 + (z0 >>> 32);
Suggestion: long result = Math.multiplyHigh(x, y); if (x < 0) result += y; if (y < 0) result += x; return result; ------------- PR: https://git.openjdk.java.net/jdk/pull/4644
