## What does NaN mean C#?

A method or operator returns NaN when the result of an operation is undefined. For example, the result of dividing zero by zero is NaN, as the following example shows. (But note that dividing a non-zero number by zero returns either PositiveInfinity or NegativeInfinity, depending on the sign of the divisor.) C# Copy.

Does C# have NaN?

“Not a Number” C# and the . Instead of producing an exception in these cases, the functions return a special value named NaN, which is an abbreviation of “Not a Number”. The NaN value can also be obtained from a constant field of the float or double structures. This field is a static member of the structure.

Is Double NaN C#?

IsNaN() is a Double struct method. This method is used to check whether the specified value is not a number (NaN). Return Type: This function returns a Boolean value i.e. True, if specified value is not a number(NaN), otherwise returns False. Code: To demonstrate the Double.

### What is double NaN value?

double nan (const char* tagp); Generate quiet NaN. Returns a quiet NaN (Not-A-Number) value of type double . The NaN values are used to identify undefined or non-representable values for floating-point elements, such as the square root of negative numbers or the result of 0/0.

How do you check if a string is a Number C#?

How to check if a string is a number in C#

1. Declare an integer variable.
2. Pass string to int. TryParse() or double. TryParse() methods with out variable.
3. If the string is a number TryParse method will return true. And assigns value to the declared integer out value.

What does NaN mean on a calculator?

In computing, NaN (/næn/), standing for Not a Number, is a member of a numeric data type that can be interpreted as a value that is undefined or unrepresentable, especially in floating-point arithmetic. …

## How do you compare NaN?

NaN compares unequal (via == , != , === , and !== ) to any other value — including to another NaN value. Use Number.isNaN() or isNaN() to most clearly determine whether a value is NaN . Or perform a self-comparison: NaN , and only NaN , will compare unequal to itself.

### What does Nan stand for in IEEE 754?

IEEE 754 floating point numbers can represent positive or negative infinity, and NaN (not a number). These three values arise from calculations whose result is undefined or cannot be represented accurately. You can also deliberately set a floating-point variable to any of them, which is sometimes useful.

When to use Nan in a method or operator?

A method or operator returns NaN when the result of an operation is undefined. For example, the result of dividing zero by zero is NaN, as the following example shows.

Can a Nan be a floating point number?

20.5.2 Infinity and NaN. IEEE 754 floating point numbers can represent positive or negative infinity, and NaN (not a number). These three values arise from calculations whose result is undefined or cannot be represented accurately. You can also deliberately set a floating-point variable to any of them, which is sometimes useful.
