# Pycharm + sage incorrect computation

I am using sage with Pycharm with sage by choosing Python2.7 from sage /bin directory like in guide in question 39742.

In computation on finite field there is bug or other incorrect behavior:

```
p = 5256107634024827443646803157596584915370839195839782329597601469354483229307063
j = 3611062252397503822281535488379195436991347721427144349104935225639485573271142
K = GF(p)
a = K((3 * j) / (1728 - j))
```

`a`

is equals `5256107634024827443646803157596584915370839195839782329597601469354483229307059`

, but in fact it should be `1674511800600631022371777328069227143110125063664501651628290807871952520681596`

.

In stand-alone sage from terminal it works correctly. What should I do for working with sage from Pycharm with correct computation.

Latest version Mac OS, sage 8.9 from Homebrew, latest version Pycharm.
