You need to create a value for a variable which is of type float and then read it as type ptr I think

$sF = Dllstructcreate("float")
 $sB = DllStructCreate("ptr",DllStructGetPtr($sF))
 
 DllstructSetData($sF,1,$Floatval)
 msgbox(262144,"ANS",DllStructGetData($sB),1)

EDIT: Corrected by adding missing parameter for the struct element in DllSTructSetData and DllStructGetData.

Yes, I didn't check what I posted. I should have written

$sF = DllStructCreate("float")
$sB = DllStructCreate("ptr", DllStructGetPtr($sF))
While 1
    $floatval = InputBox("Next value", "Enter a number, eg 123.7")
    If $floatval = "" Then Exit
    DllStructSetData($sF, 1, $floatval)
    MsgBox(262144, "ANS", DllStructGetData($sB, 1))
WEnd

This and This might also be useful.
