Context
- Context(prec=None, rounding=None, Emin=None, Emax=None, capitals=None, clamp=None, flags=None, traps=None)
Create context.
The context affects almost all operations and controls rounding,
Over/Underflow, raising of exceptions and much more. A new context
can be constructed as follows:
>>> c = Context(prec=28, Emin=-425000000, Emax=425000000,
... rounding=ROUND_HALF_EVEN, capitals=1, clamp=1,
... traps=[InvalidOperation, DivisionByZero, Overflow],
... flags=[])
