Official Solution:

If function \(ROUND(x)\) rounds \(x\) to the nearest integer while function \(TRUNC(x)\) truncates \(x\) to the largest integer less than \(x\), what is \(ROUND(2.501) - TRUNC(-1.8) - TRUNC(-0.25)\) ?

A. 2
B. 3
C. 4
D. 5
E. 6


\(ROUND(2.501) = 3\); \(TRUNC(-1.8) = -2\); \(TRUNC(-0.25) = -1\).

\(ROUND(2.501) - TRUNC(-1.8) - TRUNC(-0.25) = 3 - (-2) - (-1) = 6\).


Answer: E

Largest integer - isn't it -1 in case -1.8 and 0 in case -0.25?
