[OpenLayers-Users] limit decimal numbers

[Jon Blower]

Hi Alessio,

JavaScript 1.5+ has a toFixed() method to format numbers to a certain
number of decimal places and a corresponding toPrecision() method to
format using a certain number of significant figures.

Cheers, Jon

Subject: [OpenLayers-Users] limit decimal numbers

Hi list,

I created a function returning the current map extent and updating values
every time the user pan or zoom the map.

The function works fine and the effect is what I was looking for, but now I
need to control how many decimal numbers appear after the comma separator.
For example I want to display always 5 decimal numbers after the comma...
There's a way to do such thing?

Thanks, alessio
