To convert a
string representation of a floating-point number to a
number type, you can use the
Consider this string of floating-point number,
// string with floating point number const str = "45.67";
Let's use the
parseFloat() function and pass the
string to the function as an argument to convert it to a
number type like this,
// string with floating point number const str = "45.67"; // convert to number type const floatNum = parseFloat(str); console.log(floatNum); // 45.67
- This function is useful when you want to convert values that are obtained from
form, or whichever places where the values will be
stringtype and need to be converted to a floating-point number.
