Question

I have a quite simple task:
I must check in wchich group my float is.

Here are my groups:

• 0-30 display “(0-30)”
• 30-40 display “(0-30)”
• 40-50 display “(0-30)”
• 50-60 display “(0-30)”
• etc

I have created a simple script:

DECLARE @num FLOAT
SET @num = 42.5;
SELECT CASE WHEN @num<=30 THEN '(0-30)' 
           ELSE  '('+convert(VARCHAR,convert(INT,round((@num/10),0))*10)+'-'+convert(VARCHAR,convert(INT,round(((@num+10)/10),0))*10)+')' 
       END

I think it is a little lame, so if anyone could help me out with creating a better solution 🙂

Thanks for any advice 🙂

Use:

DECLARE @num FLOAT
SET @num = 311.2;
SELECT
CASE
    WHEN @num <= 30
        THEN '(0-30)'
    ELSE '(' + cast(cast(@num AS INT) / 10 * 10 AS VARCHAR) + '-' + cast(cast(@num AS INT) / 10 * 10 + 10 AS VARCHAR) + ')' END
