title: In R, how do I round down a decimal to the hundreth place?
body: <p>I need the number 1.558 to round down to 1.55. <code>round(1.558, 2)</code> takes it to 1.56 and <code>floor(1.558)</code> would take it to 1, but is there a function that could take it down to 1.55? Obviously, I can find another way to do it, but I want to do it in the most elegant way possible.</p>
