Build Status

This package supplies signed fixed-precision values 15 bits above the decimal, 16 bits below.

These arise commonly in GPU applications and it is chosen to match the GLfixed specification.

Changes

0.2.1.1

  • Minor documentation improvements.
  • Require base >= 4.7 properly in the source repository as the implementation uses coerce, so it doesn’t work on GHC < 7.8. This was fixed by maintenance releases to hackage previously.

0.2.1

  • Fixed bug in signum

0.2

  • Convert to/from Double to avoid precision issues.

0.1.0.1

  • Change tested-with to admit the support window is only 7.8+ at this point due to the use of Data.Coerce

0.1

  • Initial release
