Q.Predict the output of the following mathematical functions:

This checks the common numeric functions, especially the difference between ROUND and TRUNCATE.

Each part uses a mathematical function:

1. ROUND(2567.856, 2) rounds to 2 decimal places; the third decimal (6) rounds the second up, giving 2567.86.
2. TRUNCATE(2567.856, 2) keeps 2 decimal places but without rounding — it simply drops the rest, giving 2567.85. (This is the key contrast with ROUND.) …

As a check on (i) and (ii): ROUND looks at the next digit to decide whether to round up (so .856 to 2 places becomes .86), whereas TRUNCATE igno …

The commonest mistake is treating ROUND and TRUNCATE as the same. ROUND(2567.856, 2) = 2567.86 (rounded up), but TRUNCATE(2567.856, 2) = 2567.85 (chopp …
