Remainder Operator problem

Question

The remainder operator (a % b) calculates the number of multiples of b that fit within a, and returns the value that is left over, or the remainder.
I want to use remainder operator(a % b)
print(9.9 % 4)
print(9 % 4.3)
resulted output with errors.

Answer 1

As stated by the error message provided, use truncatingRemainder instead. Swift 3 no longer allows modulus operations on floating-point values.

print(9.9.truncatingRemainder(dividingBy : 4))
