Hi, I have a problem, because when I try to put a multiplication or other arithmetich function in my algorithm, and when I built it is shown an error.

I'm using a CodeWarrior for MCU 10.5.

Hi Xuuu,

Could you tell us which MCU are you using? Those seem to be floating point routines, make sure that Floing point was selected in the wizard when creating the project.

Thanks in advance!

My MCU is MCF52258, I guess the same as you, the problem is floating points, can I changed after be created the project?
