On the IAR tool, can we enable the FPU (VFPv4)? Do we have to change anything in the code (headers, function calls) to take advantage of the floating point module? How does the FPU handle double float precision?
The FPU setting with in the IAR workbench enable the compiler to use the single precision floating point unit with the Cortex processor. Just define the variable as floating point and the compiler takes care of the rest.
Double precision requires the math.h library and defining the variable as double precision floating point.
