Documentation

buildWord :: Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word64 Source

wordToFloat :: Word64 -> Float Source

Pack 23 unspecified bits from a Word64 into a Float in the range [0,1). Used to convert a stdUniform Word64 to a stdUniform Double.

wordToFloatWithExcess :: Word64 -> (Float, Word64) Source

Same as wordToFloat, but also return the unused bits (as the 41 least significant bits of a Word64)

wordToDouble :: Word64 -> Double Source

Pack 52 unspecified bits from a Word64 into a Double in the range [0,1). Used to convert a stdUniform Word64 to a stdUniform Double.

wordToDoubleWithExcess :: Word64 -> (Double, Word64) Source
