decimal places for a multiplication factor

[Greg Brown-6]

Dear group.
I am multiplying pixel values of DICOM images by a specific
number to correct for a hardware parameter.
Presently I am working with 14 decimal places, which can be
entered manually in the PROCESS MATH MULTIPLY tool, but
when I next open the tool it has contracted to 2 significant decimal
places.

I want to just check that the calculation works with the number of
decimal places entered.
( I will back well of from 14 in the next round and work with 4
decimal places)

I have read the online documenation but didn;t find an aswer, so I'd
appreciate knowing.

Thankyou
Greg

Analyze/Set Measurements... contains a "Decimal Places" input field. Maybe
this controls it?
