Agena

agena >> `The Power of Procedural Programming` 6.6.3 Shiraz, January 17, 2026 - 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) - 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. - When given a real MPFR number, `mpf.precision` now returns the precision of exactly this value. - The new real-valued MPFR constant `mpf.E` defines mpf.new(exp(1)) ~ 2.718281828.. - In the Debian editions, `mpf.beta` is now available. Issues when compiling the `mpf` package on 32-bit Debian have been fixed, too. - With complex MAPM origin (`0 + 0*I`), the `ln`, `arcsec` and `arctan` operators plus `mapm.xmulmod` and `mapm.xpowmod` now return `undefined` instead of issueing an error. `mapm.hypot4` also returns `undefined` instead of an error if the radical is negative. - `mapm.ccsch` and `mapm.csech` could crash Agena when given the origin. This has been fixed. - There has been a general problem in the `mapm` package with over-aggressive garbage collection that sometimes resulted in segmentation faults, so far experienced in Linux only. This has been fixed for all platforms. To free allocated memory that has been internally marked for deletion, call the new `mapm.trim` function if needed. - Many `mapm` functions have been tweaked a bit. - Extended the regression tests. - This release has been Valgrind-checked on x86 and x64 Linux to ensure there are no internal errors or memory leaks.
