Float Notation

In C programming, we can use the letters f or F at the end of a floating-point number to signify that it's a float. For example,

#include <stdio.h>
 
int main() {
 
    // use float notation
    float number = 36.43f;
 
    // print the variable
    printf("%f", number);
  
    return 0;
}
 
// Output: 36.430000

Notice that we've used 36.43f instead of just 36.43. This indicates that the number is of float type.

Alternatively, we can also use F to indicate that it's a float:

float number = 36.43F;

  Note: It's not compulsory to use f or F to indicate a float value. However, it's a good practice and we recommend it. But we won't be using this notation frequently in this course for the sake of simplicity..
