Re: luaeval returns number out of float

Hi Bram

Thank you for answer. 

Considering this minimal reproducing test which succeed as your,

 it doesn't come from api vim-lua, but from my own middleware vim9 script, 

I will have to look furthermore the params'values i pass. 

Ps: Forget the code and space errors, it was just the idea. 

compute.utils was just to say i use and require a lua helper script of my own. 

Vim9 client code --  vim9 export def func -- lua helper script 

minimal-test-vim9-lua-

Thank you for your help, I will see that.

I get an error for loading compute.utils:
[string "luaeval"]:1: module 'compute.utils' not found:
<09>no field package.preload['compute.utils']

Does that need to be installed first?

There are a couple of errors in the code that you should have noticed:
There should not be a space before the colons in the dictionary.

I assume you call the function with "echo Foo()"?

I cannot guess what the problem is, this appears to work fine:

def Foo(): float
return luaeval('math.pi')
enddef
