What does Nan stand for?
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 within the computing system, often a result of but by no means limited to floating-point arithmetic.
Is 0/0 a Nan?
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. For example, 0/0 is undefined as a real number, and is therefore represented by NaN.
What does Nan mean on a car listing?
Then you've probably come across a few listings that label the miles as "NaN." So what does that mean? What does "NaN" miles mean? It usually means "not a number" or that there's no value associated to the number of miles.
What is Nan in binary format?
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).
What does NaN stand for?
Not a NumberIn 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 stand for in money?
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 is NaN balance?
NaN means Not a Number and occurs when the meter is unable to process a reading to secure an outstanding balance.

How do I remove NaN error?
Q: How to remove NaN error in JavaScript? Answer: You can use if conditions with isNaN() function to remove Nan error: Note: Number. isNaN() doesn't convert the values to a Number.
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 is NaN example?
Short for not a number, in mathematics and computer programming NaN is an undefined or unrepresentable value, especially in floating-point calculations. For example, 0/0 or the square root of a negative number would return a NaN result.
What is NaN result?
Stands for "Not a Number." NaN is a term used in mathematics and computer science to describe a non-numeric value. It may also be a placeholder for an expected numeric result that cannot be defined as a floating point number.
What does NaN mean in text?
Slang / Jargon (1) Acronym. Definition. NAN. Not A Number.
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:
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 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.
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 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.
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.
