The Numeric data type
The data type of all numbers, both integer and
floating point, is Numeric. It matches any integer or floating point number, and takes no
parameters.
Numeric is equivalent to Variant[Integer, Float].
If you need to set size limits but still accept both integers and floats, you can
use the abstract type Variant to construct an appropriate data type. For
example:
Variant[Integer[-3,3], Float[-3.0,3.0]]
