下表显示了F#语言支持的所有算术运算符。 假设变量A保持10,变量B保持20然后 -

操作者描述
+添加两个操作数A + B将给出30
-从第一个减去第二个操作数A - B将给-10
*将两个操作数相乘A * B将给出200
/Divides numerator by de-numeratorB/A会给2
%模数运算符和整数除法后的余数B%A将给出0
**指数运算符,为另一个运算符提供操作数B ** A将给出20 10

例子 (Example)

let a : int32 = 21
let b : int32 = 10
let mutable c = a + b
printfn "Line 1 - Value of c is %d" c
c <- a - b;
printfn "Line 2 - Value of c is %d" c
c <- a * b;
printfn "Line 3 - Value of c is %d" c
c <- a/b;
printfn "Line 4 - Value of c is %d" c
c <- a % b;
printfn "Line 5 - Value of c is %d" c

编译并执行程序时,它会产生以下输出 -

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
Line 5 - Value of c is 1
