Conversion

Read and Show Doubles for a reasonable runtime cost.

readDouble :: Array F Char -> Double

Convert a foreign vector of characters to a Double.

• The standard Haskell Char type is four bytes in length. If you already have a vector of Word8 then use readDoubleFromBytes instead to avoid the conversion.

readDoubleFromBytes :: Array F Word8 -> Double

Convert a foreign vector of bytes to a Double.

showDouble :: Double -> Array F Char

Convert a Double to ASCII text packed into a foreign Vector.

showDoubleAsBytes :: Double -> Array F Word8

Convert a Double to ASCII text packed into a foreign Vector.

showDoubleFixed :: Int -> Double -> Array F Char

Like showDouble, but use a fixed number of digits after the decimal point.

showDoubleFixedAsBytes :: Int -> Double -> Array F Word8

Like showDoubleAsBytes, but use a fixed number of digits after the decimal point.
