7aac769d37 Modifications to transformations ... not sure which tests to run to make sure I haven't messed things up. New code avoids exponentiating values greater than -log(eps) or less than log(eps). Also changed negative code to call the positive code (I think they should inherit the positive code ... but maybe not. 2013-08-16 18:28:16 +01:00
