It would indeed be cool to have an option to change interactively the precision...preparser.set_precision? or simply set_precision? Vincent
I can look at this and propose an implementation... Thanks! t.

Nowadays -by default- all these values live in RealField(53). But, as my problem is a bit ill conditioned, I would like to compute in higher precision, say in RealField(1000). Is there a possibility to change the default behavior of say, x=1.0 x.parent() Real Field with 53 bits of precision so that: x=1.0 x.parent() gives Real Field with 1000 bits of precision ?
