floating point type

I'm working with FRDM K64F, I need to use trigonometric functions but i don't know how I can enable the floating point unit for usetrigonometric functions.

Thanks.

If you are using one of the MCUXpresso SDK projects for any M4F (e.g. K64F), then the FPU is already enabled.

Hi Carlos:

Just add one information here:

From hardware perspective, floating point setting is in devices/mk64f12/MK64F12.h

#define __FPU_PRESENT 1 /**< Defines if an FPU is present or not */

From IDE perspective, there is a Floating point configuration setting in MCUXpresso Project properties.
