Draftsight can't calculate a decimal divided by a fraction

Still trying to offset a line by using a calculation (decimal/ fraction) but the following response is given:

 

Specify distance» .355/2

Requires valid numeric distance or two points, or option keyword.

 

Anything with a decimal point that needs to be divided or multiplied seems to fail. This was never the case with previous versions.

Anyone any ideas on how to fix this?
