In JavaScript you can transform numeric strings into numbers. For example, you could easily transform the'1.5'string into a1.5float number: const numberString = '1.5'; const number = parseFloat(numberString); number; // => 1.5 When the string cannot be converted to a number, the parsing fun...
Another example is exponentiation which goes nuts when we pass NaN. Yeah, we know that “NaN turns any arithmetic operation into NaN” but for the sake of God, what is going on here? Copy >NaN**01 It’s a tricky question. Exponentiation in JavaScript does not care what exactly you are...
Example- convert NaN to 0 using JavaScript Converting NaN to 0 using Javascript // Defining Variables let x = NaN; let y = 0; // Convert NaN to 0 x = x || y; // Print the values document.write("Result: " + x); HTML Copy使用双波浪线(~~)运算符双波浪线或双位取...

In JavaScript, NaN is short for "Not-a-Number".In JavaScript, NaN is a number that is not a legal number.The Global NaN property is the same as the Number.NaN property.See Also: The Number.NaN Property The Number.isNaN() Method The isNan() Method The Infinity Property The isFinite...

.isNaN()function, which was introduced in ECMAScript 6. This function returnstrueonly if the argument isNaN, andfalsefor any other value. Unlike the globalisNaN()function, this function does not coerce the value to a number, so it only returnstruefor actualNaNvalues. Here’s an example:...
NaNis accessed using theNumberclass name. Example: Using Number.NaN // verify value is a numberfunctionverify(x){if(isNaN(x)) {returnNumber.NaN; }returnx;// only return if number is not NaN}console.log(verify(5));// 5console.log(verify(5.45));// 5.45console.log(verify(Infinity));...
