Warning
This documentation refers to the Classic QDK, which has been replaced by the Modern QDK.
Please see https://aka.ms/qdk.api for the API documentation for the Modern QDK.
Namespace: Microsoft.Quantum.Math
Package: Microsoft.Quantum.QSharp.Foundation
Returns whether a given floating-point value is not a number (i.e. is NaN).
function IsNaN (d : Double) : Bool
Input
d : Double
A floating-point value to be checked.
Output : Bool
true
if and only if d
is not a number.
Remarks
Since NaN()
is the only floating-point value that does not equal
itself, this function should be used instead of checking conditions such
as d == NaN()
.
