On Cortex-M4F microcontrollers: is fixed point math faster or floating point?

Hi,

I am using S32K14x controllers (Coretx-M4F). It has floating point math unit. I need to perform many mathematical operations as fast as possible. Which will be faster: fixed point q16 or fixed point q32 or single precision (32 bit) floating point?

Regards,

Pramod
