OCaml mod function returns different result compared with %

Python is a bit different in its usage of the % operator, which really computes the modulo of two values, whereas other programming languages compute the remainder with the same operator. For example, the distinction is clear in Scheme: In Python: But in OCaml, there’s only mod (which computes the integer remainder), according to this table and as stated in the documentation: Of course, you can implement … Read more

Assembly Language – How to do Modulo?

If your modulus / divisor is a known constant, and you care about performance, see this and this. A multiplicative inverse is even possible for loop-invariant values that aren’t known until runtime, e.g. see https://libdivide.com/ (But without JIT code-gen, that’s less efficient than hard-coding just the steps necessary for one constant.) Never use div for known powers of 2: it’s much slower than and for remainder, … Read more

How to make sense of modulo in c

The modulo operator in C will give the remainder that is left over when one number is divided by another. For example, 23 % 4 will result in 3 since 23 is not evenly divisible by 4, and a remainder of 3 is left over. If you want to output whether or not a number … Read more
