The method does not normalize, it does just this:
https://github.com/openjdk/jdk/blob/739769c8fc4b496f08a92225a12d07414537b6c0/src/java.base/share/native/libjava/Float.c#L34-L43

Theres also no `rawIntBitsToFloat`. You only need to take care of writing a float to outside the JDK, when it reads it in the normalization does not matter.
