I'm trying to take a total of 1090.91 off a grand total of 4363.64. So after taking 1090.91 off 4363.64 four times I should get 0. But pd gives me -0.000244141 ! Why is this? and is there anyway in pd I can get pd to give the correct answer of 0? Am I missing something? (I've included an example patch to help).
Thank you in advance.
