The NumericClass(x) function returns the class of x represented as a type. The class of x is described by a Maple type that recognizes

- the computation environment, and

- the numerical type of x.

If x is complex, then NumericClass(x) returns as narrowly constrained a type as possible to recognize x. To obtain precise information about the real and imaginary part of x separately, use NumericClass(Re(x)) and NumericClass(Im(x)).

The NumericClass command is thread-safe as of Maple 15.

For more information on thread safety, see index/threadsafe.
