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 .

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 the plural pronoun "nan"?
The third person plural pronoun nan (“they”) and the overall plural noun suffix -nan are unique for Papiamentu and cannot be found in any other language. According to Clements and Parkvall the pronoun nan and it's derived suffix -nan were introduced into the language just in the 1700s because of the grown need for a plural marking. Apparently before the introduction the need for a plural marking was not felt. Just like in other South American languages the suffix originated in the form "kas-nan" literally "house-they" (ac Lenz).

A comparison with a NaN always returns an unordered result even when comparing with itself.

Overview
In computing, NaN , 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. 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 and is therefore represented by NaN in computi…
Encoding
In IEEE 754 standard-conforming floating-point storage formats, NaNs are identified by specific, pre-defined bit patterns unique to NaNs. The sign bit does not matter. Binary format NaNs are represented with the exponential field filled with ones (like infinity values), and some non-zero number in the significand field (to make them distinct from infinity values). The original IEEE 754 standard from 1985 (IEEE 754-1985) only described binary floating-point formats, and did not sp…
Floating point
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. An invalid operation is also not the same as an arithmetic overflow (which might return an infinity) or an arithmetic underflow (which would return the smallest normal number, a subnormal number, or zero).
Function definition
There are differences of opinion about the proper definition for the result of a numeric function that receives a quiet NaN as input. One view is that the NaN should propagate to the output of the function in all cases to propagate the indication of an error. Another view, and the one taken by the ISO C99 and IEEE 754-2008 standards in general, is that if the function has multiple arguments and the output is uniquely determined by all the non-NaN inputs (including infinity), then that val…
Integer NaN
Most fixed-size integer formats cannot explicitly indicate invalid data. In such a case, when converting NaN to an integer type, the IEEE 754 standard requires that an invalid operation exception be signaled. For example in Java, such operations throw instances of java.lang.ArithmeticException. In C, they lead to undefined behavior, but if annex F is supported, the operation yields an "invalid" floating-point exception (as required by the IEEE standard) and a…
Display
Different operating systems and programming languages may have different string representations of NaN.
Since, in practice, encoded NaNs have a sign, a quiet/signaling bit and optional 'diagnostic information' (sometimes called a payload), these will occasionally be found in string representations of NaNs, too. Some examples are:
