Modulus

Note that modulus and remainder are not the same in case either a or b is negative. If you work with negative numbers, modulus is always non-negative (it matches the sign of the divisor).

Usage

mod(a, b)

Arguments

a

Dividend

b

Modulus

Examples

# mod(a, b) is the same as a %% b

a = 7; b = 3
rem(a, b)
#> [1] 1
mod(a, b)
#> [1] 1
a = -7; b = 3
rem(a, b)
#> [1] -1
mod(a, b)
#> [1] 2
a = 7; b = -3
rem(a, b)
#> [1] 1
mod(a, b)
#> [1] -2
a = -7; b = -3
rem(a, b)
#> [1] -1
mod(a, b)
#> [1] -1
