JavaScript parseInt() Method - W3Schools How to convert integers to hex string in JavaScript? The way this function works is that it tries to convert the whole string into a number and then evaluate the result, meaning the string must be a valid string for it to work: The Math.ceil() function is the opposite of Math.floor() since it converts a string into a number and rounds it up to the nearest whole number: Similarly to the previous examples, the Math.ceil() function will return NaN when it encounters a non-numerical value in the string: Multiplying by 1 is one of the fastest ways of converting a string to a number: And if you want to perform type conversion on a float, multiplying by 1 reserves the decimal place: If the string contains non-numerical characters, it will return NaN: This way of converting strings to integers also works with dividing a string by 1: At this point, it is also worth mentioning what happens when you try to add 1 to a string to convert it into an integer.
