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 FloatIEEE754 = FloatIEEE754 (ManagedPtr FloatIEEE754)
newZeroFloatIEEE754 :: MonadIO m => m FloatIEEE754
noFloatIEEE754 :: Maybe FloatIEEE754
getFloatIEEE754VFloat :: MonadIO m => FloatIEEE754 -> m Float
setFloatIEEE754VFloat :: MonadIO m => FloatIEEE754 -> Float -> m ()

Properties

vFloat

the double value

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

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 () Source #

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

set floatIEEE754 [ #vFloat := value ]
