Description
The FloatIEEE754 and DoubleIEEE754 unions are used to access the sign,
mantissa and exponent of IEEE floats and doubles. These unions are defined
as appropriate for a given platform. IEEE floats and doubles are supported
(used for storage) by at least Intel, PPC and Sparc.
Synopsis
- newtype DoubleIEEE754 = DoubleIEEE754 (ManagedPtr DoubleIEEE754)
- newZeroDoubleIEEE754 :: MonadIO m => m DoubleIEEE754
- noDoubleIEEE754 :: Maybe DoubleIEEE754
- getDoubleIEEE754VDouble :: MonadIO m => DoubleIEEE754 -> m Double
- setDoubleIEEE754VDouble :: MonadIO m => DoubleIEEE754 -> Double -> m ()
Exported types

newZeroDoubleIEEE754 :: MonadIO m => m DoubleIEEE754 Source #
Construct a DoubleIEEE754 struct initialized to zero.
noDoubleIEEE754 :: Maybe DoubleIEEE754 Source #
A convenience alias for Nothing :: Maybe DoubleIEEE754.
Properties
vDouble
the double value
getDoubleIEEE754VDouble :: MonadIO m => DoubleIEEE754 -> m Double Source #
Get the value of the “v_double” field.
When overloading is enabled, this is equivalent to
get doubleIEEE754 #vDouble
setDoubleIEEE754VDouble :: MonadIO m => DoubleIEEE754 -> Double -> m () Source #
Set the value of the “v_double” field.
When overloading is enabled, this is equivalent to
setdoubleIEEE754 [ #vDouble:=value ]
