Microcontrollers with Floating Point Hardware
The Cortex-M4 devices include a FPU. Some of them are:


ST Micro: STM32F3 and STM32F4 
TI: Stellaris LM4F 
NXP: LPC4300
Freescale: Kinetis K


[Edit]

Just because they include an FPU doesn't mean the support all floating point instructions. Make sure to check the microcontroller's information to see what might be missing.
