Confusion in CHDOGS's Output statement

Can someone clarify me what this means


For each test case, output a single line containing a real number corresponding to the answer of the problem. The answer will be considered correct if its absolute or relative error does not exceed 10-6.

if 6 digits after point matches the answer then it is correct.
a.ABCDEFvcybkk ans-a.ABCDEFjgoiohi correct

U r not supposed to ask something about contest problem this is output related problem u could ask it straight.
