Hi,

I'm trying to print float type data like this.

-----------------------

#include <stdio.h>

float data=0.123;

printf("%f",data);

----------------------

but, it shows empty in console display. No syntax ,build error before Run.

i tried %e , %g  and it also showed same results.

for integer type, it works. so i don't know how to solve.

Just saw your other post saying that you are trying to run this in Nios tool.

Ignore my question.

I will assign this to Nios engineer.
