Weakly less than to mean less than or equal to

Strictly less than really means the same as less than.  This is unfortunate, since it would be nice to have short phrases for less than or equal to.

Weakly less than can substitute.  3 is weakly less than 3.

Less than or equal requires a pause.

Some other possibilities.

2 underpins 3.

3 underpins 3.
