Description
Returns the integer and the fractional value of a number.
(number) (number) = math.modf(value)
Parameters
value: (number) number value
Return values
Returns (number) the integer value of the number
Returns (number) the fractional value of the number
Example
-- grid settings
local totalitems = 30 -- total number of items to put in a grid
local colsplit = 4 -- number of columns (you choose)
-- calculate number of rows
local rows, frac = math.modf(totalitems/colsplit) -- integer and fractional values
if frac > 0 then rows += 1 end -- if there is a fraction increase number of rows by 1
