2 cze 2017 · Output: 5.489500. We can generalize above method using pow () float newPrecision(float n, float i) . { . return floor(pow(10,i)*n)/pow(10,i); . } In C, there is a format specifier in C. To print 4 digits after dot, we can use 0.4f in printf (). Below is program to demonstrate the same. // C program to set precision in floating point numbers .
Example. float myFloatNum = 3.5; printf ("%f\n", myFloatNum); // Default will show 6 digits after the decimal point. printf ("%.1f\n", myFloatNum); // Only show 1 digit. printf ("%.2f\n", myFloatNum); // Only show 2 digits. printf ("%.4f", myFloatNum); // Only show 4 digits. Try it Yourself ».
