30/15rem outputs 2 instead of 2rem

[regisphilibert]

Problem appeared for me with the latest CodeKit but this has been reproduced using most recent version of less.js
Exemple :
LESS
@fontRem = 17rem;
.whatever{
font-size:25/@fontRem;
}
CSS OUTPUT
.whatever{font-size:1,47058824}
(unit is absent)
Used to be
.whatever{font-size:1,47058824rem}

This only fails with the / operator and only if left unit is absent.
30rem/15rem does output 2rem

Strict unit is set to default (off)

looks like behaviour changed in v2 and probably shouldn't have.

with strict units it is correct because the final unit of your output is "1/rem"

I have the same issue with em-units!

It does seem that units should be preserved according to the docs: http://lesscss.org/features/#features-overview-feature-operations

"If a unit is used in an operation... Less will use that unit for the final output."
