Arithmetic Operators

Description

These binary operators perform arithmetic on vector objects.

Usage

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

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.
