Can numbers be rounded (math term) using LESS CSS?

Question

LESS CSS = http://lesscss.org/

I declared a variable, like this... @height: 30px

Then I used a simple calculation, like this... line-heigh

Answer 1

http://lesscss.org/functions/ for a list of the lesscss functions, floor is included under the heading "Math functions".

Answer 2

Yes they can:

line-height: ceil(@height * .666);      // 20px (round up)
line-height: floor(@height * .666);    // 19px (round down)
line-height: round(@height * .666);     // 20px (round to closest integer)
line-height: round(@height * .666, 1);  // 20.0px (round to 1 decimal place)
