RE: Writing binary data

Check out the string.char and string.byte functions.

Hello

Is there any way to write to file the binary representation of a
lua_Number without using a custom module? I'd like the following to
work:

local myNumbers = { 0.0, 1.0, 2.0, 3.0, 4.0 }
local myFile = assert( io.open( "myFile.dat", "wb" ) )
for i=1, #myNumbers do
	-- Write myNumbers[i] to file here as binary, 
	-- as if in C we had called 
	-- fwrite( &myNumbers[i], sizeof(myNumbers[i]), 1, myFile )
end


Thanks,
Daire
