How can I make use of the FPU?
I see that the LPC4088 has an on board FPU, how can I make sure my code is using this extra power?

Hello,
if you are using online compiler, target LPC4088 has set FPU, you can check it on github,
https://github.com/mbedmicro/mbed/blob/master/workspace_tools/targets.py#L177
which then translates into cpu type - Cortex-M4.fp.

Along the same theme, what considerations should be made to make sure its being used optimally? For example, the FPU only works on single precision floats, right? So I assume that means i must avoid using double precision floats because that would resort back to software computation.
Are there any other "rules" to keep in mind?
Thanks
