Thanks for your detailed analysis, it matches my variant, so I prefer keeping FloatMath with fewer methods. I agree min/max can use jdk math as I manually inlined important calls inside very hot loops in Renderer. Here is my latest version of FloatMath (jdk branch): https://github.com/bourgesl/marlin-renderer/blob/jdk/src/main/java/sun/java2d/marlin/FloatMath.java Marlin renderer 0.9.4.5 has few more patches that I have to propose to openjdk/jdk as I did for openjfx: https://github.com/openjdk/jfx/pull/674 Thanks ------------- PR: https://git.openjdk.java.net/jdk/pull/7097
