some lua questions

[SpaceDuck]

hello!

im currently in the process of making my own addon that has some sort of function other than minor textures and band aid fixes to other addons. just have a few questions on issues im having with

1. when im calling the cooldown time remaining (using (start + duration) - seconds from GetSpellCooldown() and GetTime() ) it returns more digits than i need, ie 23.36700000002. any way to shorten it?

2.- fixed-

3. resetting the Backdrop of a frame its a bit dodgy, it would reset happily like 4 times then it would stop resetting. am i doing something wrong? first thing im doing in a function is pointing a local to a blank texture, then later in the function im pointing it to another file path that was obtained in an event -- fixed? i think?

might add more questions later, but for now would love some help! you lovely mmo champion people you

edit:

-fixed-

1. math.floor(x)

or something like

cut = strlen(x)

x = x / 1x10^cut

edit

you could then use cut like

cut = cut-4 (for 2 decimal places)

then proceed with x = x / 1x10^cut

that makes little sense to me how would i implement it?

heres what i have for my timeleft code

local timeleft = (start + duration - seconds)

local tr = iconframe:CreateFontString()
tr:SetPoint("BOTTOM")
tr:SetSize(40, 40)
tr:SetFont("Fonts\\FRIZQT__.TTF", 11, "OUTLINE")
tr:SetText(timeleft)

edit

oh another thing, errors out when an item triggers UNIT_SPELLCAST_FAILED. anyway to make it so it only detects abilities and not items?

[Yohassakura]

function round(num, dp)
  local mult = 10^dp
  return math.floor(num * mult + 0.5) / mult
end

timeleft = num
dp = decimal point (23.02) = 2dp

local timeleft = (start + duration - seconds)

local mult = 10^2
timeleft = math.floor(timeleft * mult + 0.5) / mult

local tr = iconframe:CreateFontString()
tr:SetPoint("BOTTOM")
...

Alternatively:

local function round(num,digits)
    return tonumber(("%%.%df"):format(digits):format(num))
end
