[sage-support] arbitrary precision arithmetic by default

2009-12-31 Thread eliot brenner
Is there a way to make all floating point calculations within a program or session occur to a fixed precision, say 500 digits? I know how to issue commands like R500 = RealField(500) #set up 500 bit precision arithmetic R500(pi) etc. for an individual calculation. But it would be preferable t
