Boolean objects identified by keyword true or false. It
can be used as the values of the array elements as well as
dictionary entries.
Numeric objects consist of two main types, namely integer
objects and real objects. Integer objects is representation of
mathematical integer number, whereas real objects approximate
mathematical real numbers, with limited range and precision.
Integer numbers are written as one or more decimal
digits, optionally preceded by sign, and possibly converted
to real objects if it exceeds the implementation limit. A real
value is written in the similar fashion with integer, with an
optional sign, a leading, trailing, or embedded period. Unlike
the integer objects, if the value of real objects exceeds the
implementation limit, an error will occurs.
