Floating point operations - MC9S12DP512.

[kp2309]

Hi,

Our project involves the use of MC9S12DP512. Till the time we were not using floating point operations because of limited application. Now we are building an application wherein we need to use interpolation methods algorithm. For that we want floating point operations support, but currrently i tried but event after declaring all variables float, the operations like division, multiplication is not resulting in float result.

Can anyone tell me the controller i specified supports floating point operations?if yes, is there any particular way i should follow and what is it???

Thanks n Regards,

KP

Float numbers are handled by software, not hardware.

You need to specify that you want to use float numbers when creating a new Codewarrior project, or they won't work.

While creating project i have selected floating point support.

But it is not giving the answer of any division or multiplication in float.

Could you be more specific and explain what this means
