In current programming arena most of developers use Double data type as place of Float data type. When bitSize=32, the result still has type float64, but it will be convertible to float32 without changing its value. The method only accepts one parameter and that is also optional to use. In the parameters part of the pcell code is defined like w2 to w25 as strings.I have to give the values in string(ex: "2.0u").But in the dody of the code all operations are done using w2 to w25 as float values(ex: 2.0). We don’t need to import any extra module and we don’t need any complex procedure to do it.
