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'.

How can I get MySQL to not display trailing zeros;

i.e. in the database:

Odds
1.500
23.030
2.000
4.450

would display as

1.5
23.03
2
4.45

Thanks for any help

Answer 1

Easiest way by far, just add zero!

Examples:

SET      @yournumber1="1.500",      @yournumber2="23.030",     @yournumber3="2.000",     @yournumber4="4.450" ;  SELECT      (@yournumber1+0),     (@yournumber2+0),     (@yournumber3+0),     (@yournumber4+0) ;  +------------------+------------------+------------------+------------------+ | (@yournumber1+0) | (@yournumber2+0) | (@yournumber3+0) | (@yournumber4+0) | +------------------+------------------+------------------+------------------+ |              1.5 |            23.03 |                2 |             4.45 | +------------------+------------------+------------------+------------------+ 1 row in set (0.00 sec) 

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`;
