Hi,

 

 

so, is there a way to round parameters of tfw file (e.g. 6 decimal places) while writing a tiff file.

 

 

I'm having a problem since FME changes the last (10th) decimal place of tfw file. And I'm using no transformers whatsoever.

 

 

PS. The resolution of original tiff is 0.2 and the last decimal of output tiff is 4. Does this have any correlation or is it just coincidence?

Hi,

 

 

this sounds more like the general limitation of floating point arithmetic on computers than it does a problem with FME. See here for more info: http://floating-point-gui.de/formats/fp/

 

 

If you need to round of the coordinates, try using a CoordinateRounder.
