兀怎么编程序

使用Visual FoxPro (VF):

```vb

s = 0

FOR i = 1 TO 1000

s = s + (1 / (2 * i - 1)) * (-1)^(i - 1)

NEXT

s = s * 4

? "兀约等于", s

```

使用Fortran:

```fortran

PROGRAM CalculatePi

IMPLICIT NONE

INTEGER :: i

REAL :: pi, sumsum = 0.0

DO i = 1, 1000000

sumsum = sumsum + 4.0 / (2 * i - 1)2

END DO

pi = sqrt(6 * sumsum)

PRINT *, "The value of pi is: ", pi

END PROGRAM CalculatePi

```

使用Python:

```python

import math

def calculate_pi(n):

pi = 0

for i in range(n):

pi += (-1) i / (2 * i + 1)

return 4 * pi

print("π ≈", calculate_pi(10000))

print("π =", math.pi)

```

这些程序分别使用VF、Fortran和Python编程语言,通过不同的数学公式和算法来计算π的近似值。你可以根据自己的需求和熟悉程度选择合适的编程语言和程序进行尝试。
