符号 | 描述 |
---|---|
+(更多) | 它增加了两个值 |
-(减, 减) | 它减去两个值 |
*(乘法, 倍) | 它将两个值相乘 |
/(除以) | 它用来划分 |
%(模数, 模) | 返回除法运算的余数 |
**(幂运算) | 它执行指数运算 |

let addition = add (10, 10)
let subtraction = sub (50, 20)
let multiplication = mul (10, 10)
let division = div (10, 2)
let modulus = modu (10, 3)printfn "--------------------Result------------------"
printfn "sum = %d" addition
printfn "subtraction = %d" subtraction

sum = 20
subtraction = 30
multiply = 100
division = 5
modulus = 1
F#一元算术运算符
符号 | 描述 |
---|---|
+(正数) | 它适用于算术表达式。它不会改变价值的迹象 |
-(negative, negation) | 它适用于算术表达式。它改变了价值的象征。 |
符号 | 描述 |
---|---|
=(平等, 等于) | 这不是赋值运算符。它仅用于比较。这是一个通用运算符。 |
> (greater than) | 它是一个通用运算符 |
< (少于) | 它是一个通用运算符 |
> =(大于或等于) | 它是一个通用运算符 |
< =(小于或等于) | 它是一个通用运算符 |
< > (不等于) | 它是一个通用运算符 |

b) then
printfn "A is less than B"
if(a>
b) then
printfn "A is greater than B"
if(a=b) then
