What happens if I do operations with overflow of decimal data type? Would it generate NaN?

What happens if I do operations with overflow of decimal data type? Would it generate NaN?

In Java, if you perform operations that result in an overflow of a decimal data type, such as float or double, the value will not be NaN (Not a Number). Instead, the value will be represented as either positive or negative infinity.

For example, if you add a very large number to Double.MAX_VALUE, the result will be Double.POSITIVE_INFINITY. Similarly, if you subtract a very small number from Double.MIN_VALUE, the result will be Double.NEGATIVE_INFINITY.

It's important to note that infinity is still a valid numerical value in Java and can be compared using relational operators. However, arithmetic operations involving infinity can lead to unexpected results or errors if not handled properly.

To check for overflow conditions when performing arithmetic operations on decimal data types in Java, you can use methods like isFinite() from the Double class or check for specific values like Double.POSITIVE_INFINITY and Double.NEGATIVE_INFINITY.

Overall, when dealing with operations that may result in overflow of decimal data types in Java, it's essential to be aware of how infinity is represented and handle these cases appropriately to prevent unexpected behavior in your code.

NaN doesn't exist for overflows. overflows work the same as any

#

NaN appears when a number can't be properly represented using floating point

#

floating point can't account for all possible fractional numbers

#

when you try to use arithmetic to get a result that doesnt exist in floating point, you get a rounding error

Unexpected or unacceptable ig...

since you used x *= 10, you're changing the base result

so things like x * 0 is actually infinity * 0

its just how we try to represent infinity, in the context of numbers

#

So, Infinity / 0 is infinity, i got it..

It makes sense actually

...ok?

Um just some fixed constant like values?

#

That are determined before operations...?
