Fortran-算術演算子
次の表は、Fortran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5を保持し、変数 B が3を保持すると仮定します-
Operator | Description | Example |
---|---|---|
+ | Addition Operator, adds two operands. | A + B will give 8 |
- | Subtraction Operator, subtracts second operand from the first. | A - B will give 2 |
* | Multiplication Operator, multiplies both operands. | A* B will give 15 |
/ | Division Operator, divides numerator by de-numerator. | A/B will give 1 |
* * | Exponentiation Operator, raises one operand to the power of the other. | A* *B will give 125 |
例
Fortran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-
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
上記のプログラムをコンパイルして実行すると、次の結果が生成されます-
c = 125
c = 15
c = 1
c = 8
c = 2
