How does JavaScript's parseFloat function work?
An example of an AI chatbot conversation about JavaScript's parseFloat function.
Can you explain how the parseFloat function works in JavaScript?
Sure! The parseFloat function in JavaScript is used to convert a string into a floating-point number.
What happens if the string can't be converted?
If the string can't be converted, parseFloat will return NaN, which stands for 'Not-a-Number'.
Can you give me an example of using parseFloat?
Of course! For example, parseFloat('3.14') will return 3.14, while parseFloat('abc') will return NaN.
Are there any common pitfalls when using parseFloat?
Yes, one common pitfall is that parseFloat will ignore any non-numeric characters after the number, so parseFloat('3.14abc') will return 3.14.
