What is the full form of Nan?
For other uses, see Nan (disambiguation). 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.
What does Nan mean in a monitor?
Here, the NaN is an acronym that means “Not a Number”. This term is mostly used in mathematics and computer science. It indicates that the monitoring system is not receiving any numeric data. However, there can be several reasons that are why you are receiving a NaN error. Thus, a few of them are listed below for you.
What operations can return Nan?
There are three kinds of operations that can return NaN: Most operations with a NaN as at least one operand. Indeterminate forms: The divisions (±0) / (±0) and (±∞) / (±∞). Real operations with complex results, for example: The square root of a negative number.
How do you determine the type of Nan?
The most significant bit from x is used to determine the type of NaN: "quiet NaN" or "signaling NaN". The remaining bits encode a payload (most often ignored in applications).
What does NaN mean in shipping?
Not a NumberNaN is short for Not a Number.
What is the full meaning of NaN?
In computing, NaN, standing for not a number, is a numeric data type value representing an undefined or unrepresentable value, especially in floating-point calculations.
What does NaN mean in payment?
NaN usually means Not a Number.
What is someone's NaN?
countable noun. Some people refer to their grandmother as their nan. [British, informal]
What type is NaN?
What's the typeof NaN ? The type of NaN , which stands for Not a Number is, surprisingly, a number. The reason for this is, in computing, NaN is actually technically a numeric data type. However, it is a numeric data type whose value cannot be represented using actual numbers.
What causes 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.
What does NaN mean when selling something?
Sometimes Facebook doesn't register the mileage that folks put into their listing properly and writes "NaN" (not a number). So they either have to edit the listing or adjust how they entered the values.
What does double NaN mean?

What does no NaN mean?
[no´nan] recurring on the ninth day (every eight days).
What does NaN and Pop mean?

What does nan mean in math?
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.
When was the NaN introduced?
Systematic use of NaNs was introduced by the IEEE 754 floating-point standard in 1985, along with the representation of other non-finite quantities such as infinities . In mathematics, zero divided by zero is undefined as a real number, and is therefore represented by NaN in computing systems. The square root of a negative number is not ...
What is a signaling NAN?
Signaling NaNs, or sNaNs, are special forms of a NaN that, when consumed by most operations, should raise the invalid operation exception and then, if appropriate, be "quieted" into a qNaN that may then propagate. They were introduced in IEEE 754. There have been several ideas for how these might be used:
What is the predicate for a NaN operand?
The other standard comparison predicates are all signaling if they receive a NaN operand. The standard also provides non-signaling versions of these other predicates. The predicate isNaN ( x) determines if a value is a NaN and never signals an exception, even if x is a signaling NaN.
What is the predicate for comparing with a NaN?
A comparison with a NaN always returns an unordered result even when comparing with itself. The comparison predicates are either signaling or non-signaling on quiet NaN operands; the signaling versions signal the invalid operation exception for such comparisons. The equality and inequality predicates are non-signaling so x = x returning false can be used to test if x is a quiet NaN. The other standard comparison predicates are all signaling if they receive a NaN operand. The standard also provides non-signaling versions of these other predicates. The predicate isNaN ( x) determines if a value is a NaN and never signals an exception, even if x is a signaling NaN.
What is a quiet NAN?
Quiet NaN. Quiet NaNs, or qNaNs, do not raise any additional exceptions as they propagate through most operations. The exceptions are where the NaN cannot simply be passed through unchanged to the output, such as in format conversions or certain comparison operations.
Is NaN the same as infinity?
In floating-point calculations, NaN is not the same as infinity, although both are typically handled as special cases in floating-point representations of real numbers as well as in floating-point operations.
What is a NAN?
NaN is short for N ot a N umber. NaN indicates that the monitoring system is not receiving any numeric data. There can be several causes for receiving a NaN: 1 The collectd service has stopped running. 2 The Server has crashed due to an application failure. 3 The instance has been corrupted due to a hardware failure from Amazon.
