pi.f90
I suggest you either typed this as it appears into the compiler, or as
an easier way, just copy and paste it!
Note: I do not claim
the program will 100% work, but I give it my best. If it doesn't, try tweaking
it yourself, or email me about it, and I'll modify and post the improved version
later. Good luck!
program pi_calculater
implicit none
real :: pi_answer
real :: up
real :: down
print*, "hello. pi calculater commensing. enter the number to be divided,"
print*, "then divide by what number."
print*, "number to be divided:"
read*, up
print*, "divide by:"
read*, down
if (down==0) then
stop
end if
pi_answer = up/down
print*, "answer is:"
print*, pi_answer
end program pi_calculater
