How to set FPU rounding mode of cortex M7 (IM.x RT) ?

[_ThomasLorenz_]

Hi

The is fenv.h and  fesetround() but I suppose it is only only available in c++.

How to set the FPU mode in a C project?

error: 'FE_TOWARDZERO' undeclared (first use in this function)

171 | fesetround(FE_TOWARDZERO);
| ^~~~~~~~~~~~~
*.c:171:14: note: each undeclared identifier is reported only once for each function it appears in
