Remove trailing zeros in decimal value with changing length

Question

I have a procedure I am doing that displays odds but the client wants only significant digits to be shown. So, 1.50 would show as \'1.5\' and 1.00 would show as \'1\'.

Answer 1

SELECT TRIM(TRAILING '.' FROM TRIM(TRAILING '0' from yourfield)) AS yourfield
FROM yourtable
WHERE yourfield LIKE '%.%'

or

SELECT TRIM(TRAILING '.' FROM TRIM(TRAILING '0' from yourfield)) AS yourfield
FROM yourtable
WHERE instr(yourfield,'.') != 0

work ok but require a "where" clause.

I think the best solution is probably:

SELECT TRIM(TRAILING '.' FROM TRIM(TRAILING '0' FROM ROUND(yourfield,3))) 
FROM yourtable

as it doesn't require a "where" clause, doesn't require any special code, and also lets you set the maximum precision of the number upfront.
