Does Java have NaN?

How does Java handle NaN value?

In the snippet above, you can observe that NaN is produced as a result of 3 simple operations:

  1. Dividing a float / double zero with zero.
  2. Taking under-root of a negative number (Math. sqrt(-x)). …
  3. Taking mod of a number with zero, will return the remainder after dividing a value by zero. Hence, NaN is returned.

Is double in Java?

What produces NaN?

“Nan” is produced if a floating point operation has some input parameters that cause the operation to produce some undefined result. For example, 0.0 divided by 0.0 is arithmetically undefined. Finding out the square root of a negative number too is undefined.

NaN is a property of the global object. In other words, it is a variable in global scope. The initial value of NaN is Not-A-Number — the same as the value of Number. … There are five different types of operations that return NaN : Number cannot be parsed (e.g. parseInt(“blabla”) or Number(undefined) )

Why NaN is a Number?

By definition, NaN is the return value from operations which have an undefined numerical result. Hence why, in JavaScript, aside from being part of the global object, it is also part of the Number object: Number. NaN. It is still a numeric data type , but it is undefined as a real number .
