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.06-Dec-2021

What does NaN mean in Crypto?
NumberNot a Number (NaN) represents an undefined number in floating-point operations. A Not a Number indicator may also be a sign that a variable that is supposed to be a numerical value has been corrupted by text characters or symbols.
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:
