Using floats with sprintf() in embedded C

Question

Guys, I want to know if float variables can be used in sprintf() function.

Like, if we write:

sprintf(str,\"adc_read = %d \         


        

Answer 1

Yes of course, there is nothing special with floats. You can use the format strings as you use in printf() for floats and anyother datatypes.

EDIT I tried this sample code:

float x = 0.61;
char buf[10];
sprintf(buf, "Test=%.2f", x);
printf(buf);

Output was : Test=0.61
