-- Test file to demonstrate LuaJIT tonumber routine fails on NUL char,
-- details:
--     https://github.com/tarantool/tarantool/issues/4773

local t = {
  zero = '0',
  null = '\x00',
  tail = 'imun',
}

-- Since VM, Lua/C API and compiler use a single routine for conversion numeric
-- string to a number, test cases are reduced to the following:
test:is(tonumber(t.zero), 0)
test:is(tonumber(t.zero .. t.tail), nil)
test:is(tonumber(t.zero .. t.null .. t.tail), nil)

os.exit(test:check() and 0 or 1)
