## What does FCT mean in R? ## What is a double number in R?

The two most common numeric classes used in R are integer and double (for double precision floating point numbers). R automatically converts between these two classes when needed for mathematical purposes. As a result, it's feasible to use R and perform analyses for years without specifying these differences.

Nonintegral Numeric Types

Nonintegral data types are those that represent numbers with both integer and fractional parts. The nonintegral numeric data types are Decimal (128-bit fixed point), Single Data Type (32-bit floating point), and Double Data Type (64-bit floating point). They are all signed types.
