Fortran算術(shù)運(yùn)算符

下表列出了所有Fortran語言支持的算術(shù)運(yùn)算符。假設(shè)變量A=5和變量B=3則：

運(yùn)算符 描述 例子
+ 相加運(yùn)算符，相加兩個操作數(shù)。 A + B = 8
- 減法運(yùn)算，第一操作數(shù)減去第二操作數(shù)。 A - B = 2
* 乘法運(yùn)算符，乘兩個操作數(shù)。 A * B = 15
/ 除法運(yùn)算符，通過分子除以分母。 A / B = 1
** 乘方運(yùn)算，一個操作數(shù)的B次冪。 A ** B = 125

例子

試試下面的例子就明白了所有可用的算術(shù)運(yùn)算符在Fortran語言：

program arithmeticOp

! this program performs arithmetic calculation
implicit none  

   ! variable declaration
   integer :: a, b, c
   
   ! assigning values 
   a = 5   
   b = 3  
   
   ! Exponentiation 
   c = a ** b 
   
   ! output 
   print *, "c = ", c
   
   ! Multiplication  
   c = a * b 
   
   ! output 
   print *, "c = ", c
   
   ! Division  
   c = a / b 
   
   ! output 
   print *, "c = ", c
   
   ! Addition
   c = a + b 
   
   ! output 
   print *, "c = ", c
   
   ! Subtraction 
   c = a - b 
   
   ! output 
   print *, "c = ", c
   
end program arithmeticOp

當(dāng)編譯并執(zhí)行上述程序，它會產(chǎn)生以下結(jié)果：

c = 125
c = 15
c = 1
c = 8
c = 2
