Lua-算術演算子

次の表は、Lua言語でサポートされているすべての算術演算子を示しています。 変数 A が10を保持し、変数 B が20を保持すると仮定します-

Operator	Description	Example
+	Adds two operands	A + B will give 30
-	Subtracts second operand from the first	A - B will give -10
*	Multiply both operands	A* B will give 200
/	Divide numerator by de-numerator	B/A will give 2
%	Modulus Operator and remainder of after an integer division	B % A will give 0
^	Exponent Operator takes the exponents	A^2 will give 100
-	Unary - operator acts as negation	-A will give -10

例

Luaプログラミング言語で利用可能なすべての算術演算子を理解するために、次の例を試してください-

a = 21
b = 10
c = a + b

print("Line 1 - Value of c is ", c )
c = a - b

print("Line 2 - Value of c is ", c )
c = a * b

print("Line 3 - Value of c is ", c )
c = a/b

print("Line 4 - Value of c is ", c )
c = a % b

print("Line 5 - Value of c is ", c )
c = a^2

print("Line 6 - Value of c is ", c )
c = -a

print("Line 7 - Value of c is ", c )

上記のプログラムを実行すると、次の結果が生成されます-

Line 1 - Value of c is  31
Line 2 - Value of c is  11
Line 3 - Value of c is  210
Line 4 - Value of c is  2.1
Line 5 - Value of c is  1
Line 6 - Value of c is  441
Line 7 - Value of c is  -21
