[racket] Newbie question
It's like taking a pile of cash in three different denominations and
determining the total value.
The significance tells you which digit is which. For instance, in the
number:
12,657,809.43 ;
the 3 is very insignificant to the total value of the number. So 3 is the
least significant there.
Your function signature looks good.
