Its value-range lies between '\u0000' (or 0) to '\uffff' (or 65,535 inclusive).The char data type is used to store characters. ... * float is 32 bit single precision type and used when fractional precision * calculation is required. It is recommended to use a float (instead of double) if you need to save memory in large arrays of floating point numbers. The double data type also should never be used for precise values, such as currency. © Copyright 2020 W3spoint.com.

} If you want to create a float, you should end your number with A floating-point literal is of type float if it is suffixed with an ASCII letter F or f; otherwise its type is double and it can optionally be suffixed with an ASCII letter D or dThe thing is that decimal numbers defaults to double.
