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 ...
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 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 happens if an operation produces an exception condition and traps are not masked?
If an operation can produce an exception condition and traps are not masked then the operation will cause a trap instead. If an operand is a quiet NaN, and there is also no signaling NaN operand, then there is no exception condition and the result is a quiet 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.
What is the quiet bit on a processor?
most processors (including those of the Intel and AMD 's x86 family, the Motorola 68000 family, the AIM PowerPC family, the ARM family, the Sun SPARC family, and optionally new MIPS processors) set the signaling/quiet bit to non-zero if the NaN is quiet, and to zero if the NaN is signaling.
Why does a calculation produce a NAN?
The following mathematical calculations produce NaN because the result is undefined: When a calculation involves a character, string, or other non-numeric value, the result may also be NaN. For example, 20 x "horse" does not produce a numeric result since 20 is an integer and "horse" is a string.

Is 20 x horse numeric?
For example, 20 x "horse" does not produce a numeric result since 20 is an integer and "horse" is a string. A function may return NaN as a result of invalid input, which is a preferred alternative to a program crash.

What does nan mean?
NaN. 1. Not-a-Number. These result from operations which have undefined numerical results. 2. Used to describe something for which rad, unique, unprecedented, incredible and " out of the box " are understatements, because mathematically, - NaN 'equal to' NaN is false. - NaN 'not equal to' NaN is true.
What is a NaN?
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.NaN. In modern browsers, NaN is a non-configurable, non-writable property.
Can you use NaN in a program?
It is rather rare to use NaN in a program. There are five different types of operations that return NaN: Number cannot be parsed (e.g. parseInt ("blabla") or Number (undefined)) Math operation where the result is not a real number (e.g. Math.sqrt (-1))
Overview
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 754-2008standards 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:
