Piling on another optimization: The `getZero(..)` called eagerly in the constructor is rather expensive in non-US locales, e.g. running with "-Duser.language=fr": Benchmark Mode Cnt Score Error Units StringFormat.stringFormat avgt 5 924.536 ± 253.151 ns/op Since the zero value is only used when printing floating point number I refactored so that the localized zero is evaluated lazily, which gets numbers on the micros in line with the numbers for a US locale: Benchmark Mode Cnt Score Error Units StringFormat.stringFormat avgt 5 291.385 ± 64.626 ns/op ------------- PR: https://git.openjdk.java.net/jdk/pull/2830
