Lua中關(guān)系運算符的使用教程
下表列出了所有的Lua語言支持的關(guān)系運算符。假設(shè)變量A持有10和變量B持有20則：
示例
試試下面的例子就明白了所有的Lua編程語言提供的關(guān)系運算符：
b = 10
if( a == b )
then
print("Line 1 - a is equal to b" )
else
print("Line 1 - a is not equal to b" )
end
if( a ~= b )
then
print("Line 2 - a is not equal to b" )
else
print("Line 2 - a is equal to b" )
end
if ( a < b )
then
print("Line 3 - a is less than b" )
else
print("Line 3 - a is not less than b" )
end
if ( a > b )
then
print("Line 4 - a is greater than b" )
else
print("Line 5 - a is not greater than b" )
end
-- Lets change value of a and b
a = 5
b = 20
if ( a <= b )
then
print("Line 5 - a is either less than or equal to b" )
end
if ( b >= a )
then
print("Line 6 - b is either greater than or equal to b" )
end
當建立并執(zhí)行上面的程序它會產(chǎn)生以下結(jié)果：
Line 2 - a is not equal to b
Line 3 - a is not less than b
Line 4 - a is greater than b
Line 5 - a is either less than or equal to b
Line 6 - b is either greater than or equal to b
