/********************************************************************************
* This program demonstrates use of floating-point numbers in the DE1-SoC Computer
*
* It performs the following:
* 1. reads two FP numbers from the Terminal window
* 2. performs +, 1, *, and / on the numbers, then prints results on Terminal window
********************************************************************************/

scanf ("%f", &x);
printf ("%f ", x); // echo the typed data to the Terminal window
scanf ("%f", &y);
printf ("%f\n", y); // echo the typed data to the Terminal window
add = x + y;
