[mapserver-users] How can I avoid long notation of double values in label or info template for shapes?

[Lime, Steve D (DNR)]

For completeness in a template you can use the item tag, e.g.:

  [item name="foo" precision="2"]

There is also a commify option to make big numbers look nicer. (e.g. 2,123.23)

Hi Lars,

thanks for the information!

It works fine for the label.

Before I defined LABELITEM mycolumn and got  the long notation:
2.54000000000e+000

with definition TEXT mycolumn the label looks fine (without using any
function): 2.54

Is there a solution for the query result too?

Astrid
