Rounding off to two decimal places in SQL - sql

Question

I need to convert minutes to hours, rounded off to two decimal places. I also need to display only up to two numbers after the decimal point. So if I have minutes as 650, then hours should be 10.83.
Here's what I have so far:
Select round(Minutes/60.0,2) from ....
But in this case, if my minutes is, say, 630 - hours is 10.5000000. But I want it as 10.50 only (after rounding). How do I achieve this?

Answer 1

You could cast your result as numeric(x,2). Where x <= 38.
select
round(630/60.0,2),
cast(round(630/60.0,2) as numeric(36,2))
Returns
10.500000 10.50

Answer 2

With SQL Server 2012, you can use the built-in format function:
SELECT FORMAT(Minutes/60.0, 'N2')

Answer 3

You can use:
select cast((630/60.0) as decimal(16,2))
in SQL Server

Answer 4

Declare #number float = 35.44987665;
Select round(#number,2)

Answer 5

CAST(QuantityLevel AS NUMERIC(18,2))

Answer 6

Convert your number to a Numeric or Decimal.
Replace your query with the following.
SQL Server
Select Convert(Numeric(38, 2), Minutes/60.0) from ....
MySQL:
Select Convert(Minutes/60.0, Decimal(65, 2)) from ....
The Cast function is a wrapper for the Convert function. Couple that with SQL being an interpreted language and the result is that even though the two functions produce the same results, there is slightly more going on behind the scenes in the Cast function.
Using the Convert function is a small saving, but small savings multiply. The parameters for Numeric and Decimal (38, 2) and (65, 2) represent the maximum precision level and decimal places to use.

Answer 7

DECLARE #porcentaje FLOAT
SET #porcentaje = (CONVERT(DECIMAL,ABS(8700)) * 100) / CONVERT(DECIMAL,ABS(37020))
SELECT #porcentaje

Answer 8

Try this:
SELECT CAST(ROUND([Amount 1]/60,2) AS DECIMAL(10,2)) as TOTAL

Answer 9

Following query is useful and simple-
declare #floatExchRate float;
set #floatExchRate=(select convert(decimal(10, 2), 0.2548712))
select #floatExchRate
Gives output as 0.25.

Answer 10

This works in both with PostgreSQL and Oracle:
SELECT ename, sal, round(((sal * .15 + comm) /12),2)
FROM emp where job = 'SALESMAN'

Answer 11

Whatever you use in denomination should be in decimal. For example, 1548/100 will give 15.00.
If we replace 100 with 100.0 in our example then we will get 15.48
select 1548/100
15.00000
select 1548/100.0
15.4800
0

Answer 12

As an add-on to the answers below, when using INT or non-decimal datatypes in your formulas, remember to multiply the value by 1 and the number of decimals you prefer.
I.e. - TotalPackages is an INT, and so is the denominator TotalContainers, but I want my result to have up to six decimal places.
Thus:
((m.TotalPackages * 1.000000) / m.TotalContainers) AS Packages,

Answer 13

The following snippet might help you:
select SUBSTR(ENDDTTM,1, 9), extract(DAY FROM (ENDDTTM)), ENDDTTM, BEGINDTTM, (ENDDTTM - BEGINDTTM),substr(BEGINDTTM, 1,15), substr((ENDDTTM - BEGINDTTM), 12, 8),
round((substr((ENDDTTM - BEGINDTTM), 12, 2)* 3600 + substr((ENDDTTM - BEGINDTTM), 15, 2)*60 + substr((ENDDTTM - BEGINDTTM), 18, 2)),2) as seconds,
round((substr((ENDDTTM - BEGINDTTM), 12, 2)* 60 + substr((ENDDTTM - BEGINDTTM), 15, 2) + substr((ENDDTTM - BEGINDTTM), 18, 2)/60 ), 2)as minutes,
round((substr((ENDDTTM - BEGINDTTM), 12, 2) + substr((ENDDTTM - BEGINDTTM), 15, 2)/60 + substr((ENDDTTM - BEGINDTTM), 18, 2)/3600 ),2) as hours

Answer 14

I find the STR function the cleanest means of accomplishing this.
SELECT STR(ceiling(123.415432875), 6, 2)

Answer 15

To round up to x decimal places:
SET #Result = CEILING(#Value * POWER(10, #Decimals)) / POWER(10, #Decimals)
where #Value is the value of the item to be rounded, #Decimals is the number of decimal places, for example, two in this instance.

Answer 16

This worked for me:
SELECT FORMAT(Minutes/60.0, '0.00')
