MySQL Remove Trailing Zero

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

Easiest way by far, just add zero!

Examples:

SET 
    @yournumber1="1.0", 
    @yournumber2="1.50",
    @yournumber3="10.030",
    @yournumber4="0.50",
    @yournumber5="0.0"
;

SELECT 
    (@yournumber1+0),
    (@yournumber2+0),
    (@yournumber3+0),
    (@yournumber4+0),
    (@yournumber5+0)
;

+------------------+------------------+------------------+------------------+------------------+
| (@yournumber1+0) | (@yournumber2+0) | (@yournumber3+0) | (@yournumber4+0) | (@yournumber5+0) |
+------------------+------------------+------------------+------------------+------------------+
|                1 |              1.5 |            10.03 |              0.5 |                0 |

If the column your value comes from is DECIMAL or NUMERIC type, then cast it to string first to make sure the conversion takes place...ex:

SELECT (CAST(`column_name` AS CHAR)+0) FROM `table_name`;

For a shorter way, just use any built-in string function to do the cast:

SELECT TRIM(`column_name`)+0 FROM `table_name`;
