Could G.I.A. make an error in the depth percentage on a certificate?

So 60.37 equal to 60.3 because G.I.A. does not round the number? But in mathematics, it would be right. Just think that odd not round it.

It’s not as peculiar as it sounds. The same thing happens, for example, with weights.  0.919 equals 0.91, not 0.92.  Most calculators do this too.  If you've got 8 digits, the 9th isn't rounded, it's truncated. 

It doesn't affect the conclusion in this case but 11.125=11.12, not 11.13, for the same reason.
