Lua 5.1.4
Version of implementation Lua of programming language LuaA version of Lua.
Examples:
Quadratic equation - Lua (232):
*n specifies that a number has to be read. Everything else is quite evident.
local A = io.read('*n')
if A==0 then
io.write('Not a quadratic equation.')
return
end
local B = io.read('*n')
local C = io.read('*n')
D = B*B-4*A*C
if D==0 then
io.write('x = ', -B/2/A)
else if D>0 then
io.write('x1 = ', (-B+math.sqrt(D))/2/A, '\nx2 = ', (-B-math.sqrt(D))/2/A)
else
io.write('x1 = (', -B/2/A, ',', math.sqrt(-D)/2/A, ')\nx2 = (', -B/2/A, ',', -math.sqrt(-D)/2/A, ')\n')
end
