Numeric.Fixed

Description

Fixed precision arithmetic. This format is the same format used by OpenGL ES 1's GLfixed data type:

One sign bit, 15 bits to the left of the decimal place and 16 bits to the right packed into a 32-bit integer.

Synopsis

newtype Fixed = Fixed {
- getFixed :: CInt
}
fromFixed :: Fixed -> Double
toFixed :: Double -> Fixed

Documentation

newtype Fixed Source #

A signed 2s complement 15.16 scale fixed precision number
