convert float to double!

[CovasnianuAdrian]

Hello,

I've created a polyline shapefile containing elevation values. In order to use Topo2Raster function for a Digital Terrain Model I've rapidly and by mistake created a field with float values for the elevation.
Is there a possibility to transform or to convert the float value to double values?
I need double values to work with Topo2Raster!

Thanks in advance!

You can create a new field of type Double, and then use the Field Calculator to calculate the values from the Float field to the new Double field.

TopoToRaster's input can be float, integer or double.
The output, however, will always be float (i.e 32 bit)
