parseFloat()
parseFloat() is a JavaScript function in the Global category. Parses a string and returns a float. The syntax is parseFloat(string). A typical example: parseFloat("3.14") // 3.14. A close sibling is setTimeout(), which executes a function after a delay (ms). A close sibling is clearTimeout(), which cancels a timeout. A close sibling is setInterval(), which repeatedly executes a function with a fixed delay. A close sibling is clearInterval(), which cancels an interval.
