MFFloat (3.13.0 510 API)

java.lang.Object
- com.marketfactory.zerogc.api.MFFloat

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable
```
public class MFFloat
extends java.lang.Object
implements java.lang.Comparable, java.io.Serializable
```
A thin wrapper for a fixed-precision floating point number. This class is mutable to allow for zero garbage collection operation. All static operations and the toString operation will create new objects. So keep this in mind when writing zero gc code.
