GI.GLib.Unions.FloatIEEE754

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.

Exported types

newtype FloatIEEE754

Memory-managed wrapper type.

Constructors

FloatIEEE754 (ManagedPtr FloatIEEE754)

Methods

wrappedPtrCalloc :: IO (Ptr FloatIEEE754)

wrappedPtrCopy :: FloatIEEE754 -> IO FloatIEEE754

wrappedPtrFree :: Maybe (GDestroyNotify FloatIEEE754)

tag ~ AttrSet => Constructible FloatIEEE754 tag

Defined in GI.GLib.Unions.FloatIEEE754

Methods

new :: MonadIO m => (ManagedPtr FloatIEEE754 -> FloatIEEE754) -> [AttrOp FloatIEEE754 tag] -> m FloatIEEE754

newZeroFloatIEEE754 :: MonadIO m => m FloatIEEE754

Construct a FloatIEEE754 struct initialized to zero.

noFloatIEEE754 :: Maybe FloatIEEE754

A convenience alias for Nothing :: Maybe FloatIEEE754.

Properties

vFloat

the double value

getFloatIEEE754VFloat :: MonadIO m => FloatIEEE754 -> m Float

Get the value of the “v_float” field. When overloading is enabled, this is equivalent to

get floatIEEE754 #vFloat

setFloatIEEE754VFloat :: MonadIO m => FloatIEEE754 -> Float -> m ()

Set the value of the “v_float” field. When overloading is enabled, this is equivalent to

set floatIEEE754 [ #vFloat := value ]
