Which of the following statements should be used to obtain a remainder after dividing 3.14 by 2.1 ?

A. rem = 3.14 % 2.1;

B. rem = modf(3.14, 2.1);

C. rem = fmod(3.14, 2.1);

D. Remainder cannot be obtain in floating point division.

Solution

C. rem = fmod(3.14, 2.1);

Explanation

fmod(x,y) - Calculates x modulo y, the remainder of x/y. This function is the same as the modulus operator. But fmod() performs floating point divisions.
