approché par défaut

What could be so hard. It's a multiple-choice test for Pete's sake.

approché par défaut

Hello,

I meet a problem to translate the french expression "approché par défaut" in particular in the sentence hereafter.

Theorem: Any convergent sequence in a metric space is a Cauchy sequence.
Let us notice however that the reciprocal is not true, i.e. a sequence can be a Cauchy sequence but without convergence. For example: The sequence of decimal values "approchées par défaut" of √2 is a Cauchy sequence in Q.
("approached from below" or "rounded down", or .... ???)
How translate this expression in such a case?
Thanks you for your help.
Best regards.
