%) operator allows you to get the remainder after dividing the first operand with the second operand.mod() function as well as % and modoperators (I'll just reference % for the rest of this article). % and mod() output a remainder, their output values will take the sign (+/-) of the dividend.mod() will treat it as a negative integer natively.% operator, you'll need to wrap your divisor in parentheses () in order to explicitly define your divisor as a negative integer.x % (-y) will work exactly like mod().x % -y will cause Notion to rewrite your formula as x / 100 - y, which will output an incorrect result. This is because the - is treated as a unaryMinus operator, and Notion's math engine can't correctly deal with it when it's appended to the divisor.% operator calculates the remainder of two numbers, not the modulus. Confusingly, the mod() function does this as well, despite its name.+/-). If their signs differ, however, the modulus will differ from the remainder.-19 mod 12 results in 5QuotientRemainder[-19,12] results in -7((x % y) + y) % y instead:% expressions need to be wrapped in parentheses () so Notion can parse them explicitly as negative integers (see code line 7 in the above code block). - as a unaryMinus operator, rewrite your formula to (x / 100 - y + -y) / 100 - y, and return an incorrect result. However, this isn't necessary when using the mod() function.prop() function.
