GI.GLib.Unions.DoubleIEEE754

Contents

Description

The tFloatIEEE754 and tDoubleIEEE754 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.

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

set doubleIEEE754 [ #vDouble := value ]
