Question

Is there a built-in function in MySQL the removes trailing zeros on the right?

I have samples and i want my output to be like this:

 1.0    ==>   1
 1.50   ==>   1.5
10.030  ==>  10.03
 0.50   ==>   0.5
 0.0    ==>   0

Answer 1

it solves my problem using this:

(TRIM(TRAILING '.' FROM(CAST(TRIM(TRAILING '0' FROM setpoint)AS char)))) AS setpoint

example:

mysql> SELECT testid, designationid, test, measure,
              (TRIM(TRAILING '.' FROM(CAST(TRIM(TRAILING '0' FROM setpoint)AS char)))) AS setpoint,
              (TRIM(TRAILING '.' FROM(CAST(TRIM(TRAILING '0' FROM tmin)AS char)))) AS tmin,
              (TRIM(TRAILING '.' FROM(CAST(TRIM(TRAILING '0' FROM tmax)AS char)))) AS tmax,
       FROM    tests
