* double:
* double data type is a double-precision 64-bit IEEE 754 floating

*
* This data type is generally used as the default data type for decimal
* values, generally the default choice.
*
* Double data type should never be used for precise values such as
* currency.
*
* Default value is 0.0d.
*
* Example: double d1 = 123.4

* float:

* Float is mainly used to save memory in large arrays of floating point

*
* Float data type is never used for precise values such as currency.
*
* Example: float f1 = 234.5f
