gettype()
Returns the runtime type of its single argument.
The runtime type may be different than the nominal (static) type for expressions whose nominal type is dynamic; in such cases gettype() can be useful to reveal the type of the actual value (how the value is encoded in
memory).
Syntax
gettype(Expr)
Returns
A string representing the runtime type of its single argument.
