WebIEEE 754 fordert zwei Arten von Nichtzahlen: stille NaN (NaNq – quiet) und signalisierende NaN (NaNs – signalling ). Beide stellen explizit keine Zahlen dar. Eine signalisierende NaN löst im Gegensatz zu einer stillen NaN eine Ausnahme (Trap) aus, wenn sie als Operand einer arithmetischen Operation auftritt.
