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 (useLsuffix, e.g.,10L);complex: numbers with both real and imaginary parts (useisuffix 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.
Swipe to start coding
- Assign the current year's numerical value to a variable named
year, and ensure that it is ofintegertype by appendingL. - Determine and display the type of the
yearvariable:
