Java functions to convert between floating point and normalized fixed point values.

Features

  • Conversion between unsigned normalized fixed-point numbers and floating point numbers.
  • Conversion between signed normalized fixed-point numbers and floating point numbers.
  • High coverage test suite.
  • OSGi-ready
  • JPMS-ready
  • ISC license.

Usage

Convert a floating point value to its 32-bit unsigned normalized fixed point representation:

var r = NFPUnsignedFloatLong.toUnsignedNormalized(0.25, 32);

Convert a 32-bit unsigned normalized fixed point value to its floating point representation:

var s = NFPUnsignedFloatLong.fromUnsignedNormalized(r, 32);

Classes exist for signed, unsigned, int, long, float, and double specializations.
