Arithmetic Operators

Usage

x + y
x - y
x * y
x / y
x ^ y
x %% y
x %/% y

Description

These binary operators perform arithmetic on vector objects.

Value

They return numeric vectors containing the result of the element by element operations. The elements of shorter vectors are recycled as necessary. The operators are + for addition, - for subtraction * for multiplication, / for division and ^ for exponentiation.

%% indicates x mod y and %/% indicates integer division. It is guaranteed that x == (x %% y) + y * ( x %/% y ) unless y == 0 where the result is NA or NaN (depending on the typeof of the arguments).

Objects such as arrays or time-series can be operated on this way provided they are conformable.
