Re: double precision

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Holger,
Ferret does almost all its computation in single precision. Only the 
coordinate
values of the grid are saved and used as double precision; data for 
variables is
read, used, and written as single precision.  We're aware that this is a 
limitation,
but at this time there is not a way to force Ferret to do calculations 
in double
precision.
