Converting to a Number









JavaScript has two methods for converting non-number primitives into numbers: parseInt() and parseFloat().

parseInt() converts a value into an integer.

parseFloat() converts a value into a floating-point number.

These methods only work properly when called on strings; all other types return NaN.
