select round((cast(56/3 AS DECIMAL (4,2))),1)
is showing 18 output instead of 19 , where as actual value is 18.66. My Round function is not working please help.
The problem is 56/3
is an integer calculation which means no floating point numbers.
You need to use floating point numbers in the initial calculation eg 56.0/3
. Also, if you want to round to 19 then you need to round to the nearest whole number, ROUND(x, 1)
will round to the first decimal place - you need to pass 0
to round up to 19.
SELECT ROUND((CAST(56.0/3 AS DECIMAL (4,2))),0)
Alternatively, you could switch ROUND for CEILING
select CEILING(CAST(56.0/3 AS DECIMAL(4,2)))
Your section of the code:
CAST( 56/3 AS DECIMAL )
First evaluates the 56/3
which returns 18. This is then cast to decimal, giving 18.0.
You need to cast either the numerator or denominator before the division occurs.
The round
function is working fine -- it's just not using the input you think it is.
Convert one of your integer values before you divide the numbers:
select round(56/convert(DECIMAL (4,2),3),0);
If you do not so you divide integers which results in 18 not 18.66
