cMud and exponents.
|
Hi,
I am trying to get exponents to work in cMud.
I cannot get #SHOW {x^y} to work and can't find a function for it. Am I missing something?
Thanks |

I dont think there's a built in way in CMUD.
I wrote a quick function to take advantage of the lua library to get it done.
| Code: |
<func name="math" language="Lua" id="32">
<value>if zs.numparam == 0 then return nil end
local func = zs.param(1)
if type(math[func]) ~= "function" then return nil end
local arg = {}
for i=2,zs.numparam do
table.insert(arg,tonumber(zs.param(i)))
end
return math[func](unpack(arg))
</value>
</func> |
It's just a wrapper to the Lua math library.
A description of the functions available can be found here
To use it you would do something like.
#echo @math("pow",2,4)
It would then echo 16
I had it return 'nil' if you messed up but you could just as easily change that to return an empty string or to raise an exception |
