Rounding all elements of an array

Oops, I realized that I redefined the native function "round". Not good. But my basic question remains.

I wouldn't worry unduly about redefining the native function.  I do it almost all the time when I want the native function to do something different.

By default, Mathcad will assign the "Variable" Label to your redefined function.  The original function is still available with different labels.

To see or change a name's label, click on the name, then look in either the Math tab for Labels or in the Math Formatting tab (as seen in the image below).

The tab should indicate the name's label.  The formatting tab lets you change a label's formatting to display it in a different colour or with a different attribute (bold, italic).  Unfortunately, you can't change a label's font or font size independently of the other labels.

I usually choose bold, green for the Function label, but I've changed it to red to make it stand out a bit better (hopefully).

You should be able to see in my previous post how it allows you to distinguish between the built-in round and both our redefined rounds.

Unfortunately, the element-wise rounding didn't accomplish my end goal. I wanted it to round the mantissa when working with numbers in scientific notation. Do you see an elegant way to accomplish that?
