Wanting floating point "in your program" sounds as you you want it in C code running on the Nios processor. That should work just fine. The Nios compiler handles single and double precision FP. There's no floating point hardware, though, so it's all handled in library functions - if speed is an issue, you might need to check that it runs as fast as you want.
