Can you give me some examples of using parseFloat in JavaScript?
Sure! The parseFloat function in JavaScript is used to convert a string to a floating-point number. For example, parseFloat('3.14') will return 3.14.
What happens if the string can't be converted?
If the string can't be converted, parseFloat will return NaN. For instance, parseFloat('abc') results in NaN.
Can you show me an example with a number in a string?
Absolutely! If you use parseFloat('10.5 apples'), it will return 10.5, ignoring the non-numeric part.
Is there a way to limit the number of decimal places?
You can use the toFixed method after parseFloat. For example, parseFloat('3.14159').toFixed(2) will give you '3.14'.
