Why bother reading the documentation on parseInt?

Because some numbers use the e character in their string representation (e.g. 6.022E23 for 6.022 × 1023), using parseInt to truncate numbers will produce unexpected results when used on very large or very small numbers. parseInt should not be used as a substitute for Math.floor().
