Does anyone know what the symbol “%” means in expression?
When X is 100, Y is 100, the outcome is 0.0
When X is 100, Y is 75, the outcome is 25.0

Thank you for answering it.

Modulus Component applies the modulo operation to two numbers. Given two positive numbers X and Y , X modulo Y is the remainder of the Euclidean division of X by Y.

X = nY + r : The % function gives you the “r”
