### (Math Help) How do I round to the nearest 50?

I.E.
23 = 0
27 = 50
56 = 50
79 = 100
122 = 100
143 = 150
178 = 200
994 = 1000

Basically, if the last two digits are closer to 100, then it rounds it to 100. Otherwise, if the last two digits are closer to 50, then it rounds it to 50. Or if the last two digits are closer to zero, then it rounds it to zero.

Code: Select all

function love.draw()
love.graphics.print("obey")
end

### Re: (Math Help) How do I round to the nearest 50?

first thing that comes to mind is:

Code: Select all

function roundnearest(num, to)
local rem = num % to
if rem < (to / 2) then
return num - rem
else
return num - rem + to
end
end

(then you call it with '50' as the second argument)
edit: messed it up, need sleep. fixed.

You can try the following:

Code: Select all

function roundTo ( number, multiple )
return math.floor ( ( number / multiple ) + 0.5 ) * multiple
end
