My apologies for asking again about this issue.
Different results obtain from converting to a built-in profile in memory
vs the same profile save to disk.
Is it accurate to say that the results are different because the added
precision in the profile in memory means the profile in memory

Hi Elle,
Sorry I didn't explain myself. I mean, when you actually
store a built-in profile to disk, you are forced to use
the ICC profile format. The ICC profile format has some
limitations when storing floating point numbers.

Hi,
The ICC file format stores matrix of sRGB as 15.16 fixed point, that

and addition, the final precision is

That means, if you have a floating point number
in memory that is,
There are discrepancies when converting to an lcms built-in profile,
compared to converting to the same profile previously saved to disk.
I noticed the discrepancies while testing GIMP 2.9 16-bit integer and
32-bit floating point ICC profile conversions. The same discrepancies
happen when
Hi,

and addition, the final precision is reduced to 1e-3, that means
only two decimal places are
