A signed integer.

Input Format:

A sequence of numeric digits, possibly prefixed with a sign character.

Use with do-loops:

When an Integer variable is used as the dependent variable of a do-loop, the associated loop increment is also an Integer.

Examples:

 print $Integer(123)
 -> 123

Context:

This datatype is mainly used to specify do-loop increments when the loop variable is an integral datatype.
