Float or integer

Question

0.0 is double or float. What about 0? is 0 an integer ? Is 0 a float?

Answer 1

0.0
C/C++, Java, C#: double
Python, JavaScript: float

0
C/C++, Python, Java, C#: integer
JavaScript: float*

If you want to make 0.0 explicitly float instead of double in C/C++, Java, C# then use 0.0f.

If you want to make 0 explicitly long integer in C/C++, Java, C# then use 0L.

* - JavaScript has only one number type, which is equivalent to a floating point type.

Answer 2

It depends on the context. You have not provided any context.

You can print the data type and find out.

Answer 3

Oliver Pasaribu this could be either ...

floats are generally precise within 7 decimal points

doubles are generally precise within 15 decimal points

I usually depending on the language go with double.

Answer 4

0 is many things like nullptr, NULL, false in C++. maybe it is like that in Java but Java is strict and you should add .f to make it float or widening conversion. If you do not try it, then 0 is default to integer
