Less - Math Functions

Description

Math functions includes methods which are used for performing numeric operations such as round, square root, power value, modulus, percentage etc.
Following table shows Math Functions used in LESS:

S.N. Function & Description Example
1 ceil
It rounds up the number to next highest integer.		 
       ceil(0.7)
it round the number to: 
       1
2 floor
It rounds down the number to next lowest integer.		 
       floor(3.3)
it round the number to: 
       3
3 percentage
It transforms the floating point number to percentage string.		 
       percentage(0.2)
it converts the number to percentage string as: 
       20%
4 round
It rounds a floating point number.		 
       round(3.77)
it converts the number to the rounding value as: 
       4
