[sage-devel] Default precision for floats

[Thierry Dumont]

I have a program with a lot of floating point constants/variables (this 
is a translation of a C++ program).
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
?

Yours
t.
