Question

Which of the following statements should be used to obtain a remainder after dividing 3.14 by 2.1 ?
rem = 3.14 % 2.1
rem = modf(3.14, 2.1);
rem = fmod(3.14, 2.1);
Remainder cannot be obtain in floating point division.

Answer 1

Answer: rem = fmod (3.14, 2.1);

Explanation:

Answer 2

Third statement 'rem = fmod(3.14,2.1);' should be used to obtain remainder.

Since fmod() works the same as the modulo function in every language. It returns the remainder by dividing the number.

• The First statement works with the programming languages like Python only.
• The Second statement returns the whole number of the quotient by dividing the number.
• The Fourth statement is also true for some programming languages.
