Check whether the language has different data types by using JScript.

1. templates can be used for data types, such as C ++, which is relatively simple, but C is difficult. 2. If there is no data type, it is necessary to judge all points for execution. Time is complex and time is not optimized, and the code is easy to understand. For example, test the right triangle. VaR Epsilon = 0.00000000001; // small numbers to be tested.
