Numeric Types
By default, numeric values in R are stored as double-precision floating-point numbers (double
). To use integers or complex numbers, you must mark them explicitly.
Numeric Types
double
: real numbers either with or without a decimal point;integer
: whole numbers (useL
suffix, e.g.,10L
);complex
: numbers with both real and imaginary parts (usei
suffix for imaginary part).
Example
123typeof(10) typeof(10L) typeof(10 + 5i)
Integers typically require less memory than doubles, so distinguishing between them can be important for efficiency.

- Assign the current year's numerical value to a variable named
year
, and ensure that it is ofinteger
type by appendingL
. - Determine and display the type of the
year
variable:
