The modulo operator can be incredibly useful but developers need also to be aware of the above edge cases and when to use or not use it.įor a more detailed discussion see the wikipedia article.In sum, MOD is an acronym or abbreviation word that is defined in simple language. MOD returns the remainder of n2 divided by n1. Which allows for a much faster implementation of is_odd. A simple and efficient way is to check the sign.Īt least for a positive divisor, the modulo operation can be replaced with a simple bitwise and operation. So if you use the modulo operator to ensure correct bounds for accessing a collection, beware that some languages need a little more diligence. With only one special outlier being Dart. While the code looks pretty much the same in most languages, printing the result shows languages in mostly two different camps.
Turns out the rules of modulo on negative numbers depend on the language you are using. What happens if the dividend or the divisor is signed and holds a negative value? This means that no matter the value index has, the array bounds are met. Value_at_index = valuesįor the above example this means 5 mod 3 = 2 following the definition is 5 - floor(5/3)*3 = 2. In programming, the modulo operator ( % or sometimes mod) often is used to restrict an index to the bounds of an array or length limited data structure. Subtracting this from a yields the remainder of the division and by that the modulo.īut what does modulus do? What can it be used for when coding? Later a widely accepted mathematical definition was given by Donald Knuth mod(a, n) = a - n * floor(a / n)ĭoing an integer division and then multiplying it again means finding the biggest number smaller than a that is dividable by n without a remainder. In 1801 Gauss published a book covering modular arithmetics. The modulo or often referred to as “mod” represents the remainder of a division.
