Why do we use MOD function?
The function helps find a remainder after a number (dividend) is divided by another number (divisor) . As a financial analyst.

How is mod calculated?
- Start by choosing the initial number (before performing the modulo operation). ...
- Choose the divisor. ...
- Divide one number by the other, rounding down: 250 / 24 = 10 . ...

What is mod () function?
The MOD function takes as arguments two real number operands, and returns the remainder from integer division of the integer part of the first argument (the dividend) by the integer part of the second argument (the divisor).
