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

Isn't something like this really easier:

#include 
#include 
#include 

char str[10];
float adc_read = 678.0123;

dtostrf( adc_read, 3, 4, temp );
sprintf(str,"adc_read = %10s \n", temp);
printf(temp);
