Java – interpret scientific symbols as int or float?
•
Java
If I use scientific symbols (such as 1e9) to encode a number in my code, the type of the number will be (int, long, float, double...)?
When the significant digits or exponents are floating-point numbers, they obviously cannot be integers, but in the above case?
Solution
E make it a floating point text From JLS (§ 3.10.2. Floating point literals):
Therefore, the 1e9 type is double and 1e9d On the other hand, 1e9f is floating point
