floor & ceil function- math library documentation.

Massimiliano Cecconi

Hello,

I need floor(float x) and ceil(float x) functions in my C++, CCS-4.0 allpication, but thay don't work.

I included <cmath.h> and i linked with math library rts2800_ml.lib (--library) but the compiler idicates me as unknown functions.

Any subjestion?

And.. where can i find documentation about rts2800 mathematical library?

Thank everyone.

The only versions of floor and ceil supported by C28x right now are the "double" versions.

I've tryed olso with double argument but don't worrk. The compiler indicate floor and ceil as undefiner identifier...

Any subjestion?

Your initial post says you include "<cmath.h>", but no such file exists in the RTS header files. I'm guessing you probably included "<cmath>", in which case floor and ceil are in the std namespace, not the global namespace. To use them, you will need a "using" declaration, such as:

#include <cmath>
using std::floor;

If this isn't what's going on, you may need to post a test case.
