Agena

agena >> `The Power of Procedural Programming` 6.6.5 Shiraz, January 21, 2026 - New `long.polygen` accepts a table of coefficients (Agena numbers or long double userdata) and returns a polynomial function that can be evaluated at any given point. Example: > coeff := [long.new(3), long.new(2), 1]; # coefficients in descending order > f := long.polygen(coeff); # creates f := <: x -> coeff[1]*x**2 + coeff[2]*x + coeff[3] :> > f(long.new(2)): longdouble(17) - New `mapm.ccbrt` computes the cubic root for a complex MAPM number. - New `mpf.ismpf` checks for one or more real MPFR numbers and `mpf.iccmpf` for a complex MPFR numbers, returning `true` or `false`. - New `mpf.checkmpf` and `mpf.checkcmpf` check all the arguments for real or complex MPFR numbers and issue an error otherwise. - Some `long` package functions issued confusing error messages when given a non-number or non-long double userdata value. In some cases the interpreter could even crash. This has been fixed. - Corrected error message of `mpf.swap`. - The new C API function `agnL_pushcoeffs` takes a structure of numbers or long double userdata and pushes onto the stack a userdata LongDoubleArray. - This release has been Valgrind-checked on x86 and x64 Linux to ensure there are no internal errors or memory leaks.
