[OpenJDK 2D-Dev] JDK 9 RFR of JDK-8149896: Remove unnecessary values in FloatConsts and DoubleConsts

[Laurent Bourgès]

Hello,

Joe, I tested your changes in the Marlin renderer as it works well !


> A quick note on the 2d changes, several constants (and a copy from a

> hexadecimal floating-point literal.

I agree it is simpler and exactly what I needed; I wasn't aware of such
literals:

Thanks for the fix,
