calc function not being translated propertly

[alberchou]

Good morning,

I have a less file with the following class style:

.whatever {
    width: -webkit-calc(100% - 210px);
    width: -moz-calc(100% - 210px);
    width: calc(100% - 210px); 
}

But when it is crunched to a css file, crunch does not translate it propertly:

.whatever  {
  width: -webkit-calc(-110%);
  width: -moz-calc(-110%);
  width: calc(-110%);
}

The expected style was:

.whatever {
    width: -webkit-calc(100% - 210px);
    width: -moz-calc(100% - 210px);
    width: calc(100% - 210px); 
}

May you please fix this? Thanks a lot!

Have a nice day,
Alberchou.
