Can Java work with "long double"

Answer 1

Yes, Java supports the `double` data type for representing double-precision floating-point numbers. The `long` data type, however, is specifically for integers, not floating-point numbers. If you need to work with floating-point numbers in Java, you would typically use `double` or `float` for single-precision floating-point numbers.

Example of a `double` variable in Java:

```java
double myDouble = 3.14;
```

If you need higher precision than `double`, you might consider using the `BigDecimal` class for arbitrary-precision arithmetic.

Answer 2

There is long type. ( whole numbers)
And double type. ( precision valued numbers)

No long double? What it is?

Answer 3

But take a try in cpp

Answer 4

Show me how to use long type

Answer 5

But not in java.

in java,
long num = 123457890000000_000L;

// no underscore needed but add suffix L for over integer value.
