gettype()
Learn how to use the gettype() function to return a string representing the runtime type of its single argument.
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).
