Agena for Mac

New Features

• New mpf.argument computes the phase angle (principal argument) of a real or complex MPFR number.
• New mpf.polygen: Accepts a table of coefficients (Agena numbers, real or complex MPFR numbers) and returns a polynomial function that can be evaluated at any given point. Example: > import mpf; > coeff := [mpf.new(5, 1), mpf.new(3, 1), mpf.new(1, 1)]; # complex coefficients in descending order > f := mpf.polygen(coeff); # creates f := <: x -> coeff[1]*x**2 + coeff[2]*x + coeff[3] :> > f(mpf.new(1, 0)): cmpf(9.000000000000000000000000000000000000000, 3.000000000000000000000000000000000000000)
• The new real-valued MPFR constant mpf.E defines mpf.new(exp(1)) ~ 2.718281828..

Fixes

• Many MPFR functions mixed rounding modes internally which only became an issue if the user changed the default rounding mode, causing slightly wrong results. This has all been fixed.

Changes

• When given a real MPFR number, mpf.precision now returns the precision of exactly this value.
• In the Debian editions, mp
