trunc and round function in sql
18,746
Solution 1
No, behavior depends on the value of the significant digit (the 3rd digit (the 3) is the significant one in your case, as it is below 5 round
and trunc
do the same )
try select trunc(125456.76,-4) from dual
(result is 120000) vs select round(125456.76,-4) from dual
(result is 130000). Now when the significant digit is 5 (or higher) the results of trunc
and round
differ.
Solution 2
ROUND

TRUNC
is related to truncation of given values.
In round
case of given example, four places till 4th place prior to decimal point padded with 0.
But in trunc
case, four places till 4th place prior to decimal point replacd with 0.

Is trunc and round the same with negative arguments?
SQL> select round(123456.76,-4) from dual; ROUND(123456.76,-4) ------------------- 120000 SQL> select trunc(123456.76,-4) from dual; TRUNC(123456.76,-4) ------------------- 120000
