digits on basic dim and the tolerance 2

[nry67]

Hi somebody can help me to found the information concerning the precision of dim and tol. Value in mm.

I know it's possible to have : 4+/-0.2 or an other exemple 4.2+/-0.5
My question is, Is it possible to indicate on a drawing this exemple : 4.25+/-0.1

To me it's strange to use 2 digits on the dim and only 1 in the tolerance.

Thank you

So, to limit the waste of parts that could be good it is better to review the information on the drawing because a control for 0.1 is done by caliper while for 0.001 you need a specific control tool.
