"10 decimal places" is used here to mean ten digits after the point (1a.bcdefghijk), but it can also be understood to mean ten digits in total (1a.bcdefghi). That could use some clarification.

It is 10 places behind the decimal point.

I know, but it could still be clarified.

"10 significant digits" and "10 decimal places" are two terms that look interchangable, but mean different things. That difference could be made clearer in many problems such as this one.
