Order-preserving encryption in Java

Hi, thanks for your work of this open source project! :) I am trying to use your code on some project and is stuck by a problem. The following are the parameters I used to test the program.
this.inRange = new ValueRange(BigInteger.ZERO, new BigInteger("2").pow(40));
this.outRange = new ValueRange(BigInteger.ZERO, new BigInteger("2").pow(41));
this.key = "key11"
The plaintext is new BigInteger("948980387264"); then the program enters into an endless while loop
of function hypergeometricHyp.
I checked the values within in the function and found this happened when Y = 1, inner = 0 and K = 0. K = 0, K -- will make it never run the break. And inner = 0, then Y will always be larger than 0.
Did you know how to fix this issue? Your help will be appreciated very much!
Hi,
thank you for this code,
I had this problem, could you help me please:

BigDecimal d9 = BigDecimal.valueOf(1.9999542254);
BigDecimal d = loggam(d9.add(BigDecimal.ONE));
System.out.println(d); //-0.000019352145145910313920070482
correct value is 0.69310494089 (https://www.wolframalpha.com/input/?i=loggamma%281.9999542254+%2B+1%29)
it's giving the value of loggamma(d9)
not loggamma(d9+1)
which is curious. It wouldn't matter if you called loggamma(d9)
but you're calling loggamma(d9+1)
so I think it's incorrect?
