Changes for version 2.099 - 2025-01-23

  • fix test that assumed acosh(0)->byte, i.e. nan()->byte, was always 0 (#514) - thanks @eserte for report
  • separate PDL::Type POD documentation
  • partly restoring pre-2.096 xform type-selection: if xform given no typed outputs, and non-available (greater than last-given type) typed inputs, use last-given (#511, https://github.com/moocow-the-bovine/PDL-CCS/issues/18)
  • fix Math::polyroots with native-complex input and supplied null output
  • add Pars type-spec "!real" which makes it an error to supply real values (#511)
  • now an error to call Ops::carg on a real value, or Ops::czip on complex inputs (#511)
  • fix packsize for indx to base on ptrsize, not ivsize (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1092246) - thanks Helge Deller for report
  • now an error to upd_data if datasv set to different size from nbytes
  • add PDL::readonly method (#516) - thanks @wlmb for suggestion
  • rename Ufunc::diffover to Ufunc::numdiff (#516)
  • add Ufunc::{diffcentred,partial} (#516)
  • fix xforms without [o] Pars not getting bvalflag set, a regression in 2.083 (#517) - thanks @vitstradal for report
  • Ops::ipow now actually works inplace like doc says (#519)
  • InplaceDoc now automatically generated like BadDoc, Signature doc includes types
  • Overload key added to PP (#519)
  • "usage" section of xform docs now automatically generated (#519)
  • overloaded operators now throw exception if given undef argument (#519) - thanks @cgtinney for report
  • Core::dog now scales linearly with length of top dim, not O(n^2) (#421) - thank @djerius for report
  • PDL::IO::Storable now also supports Sereal, JSON::MaybeXS, CBOR::XS (#510,#520) - thanks @shawnlaffan
  • add ParamDesc PP key
  • fix IO::Pic problem with older IO::GD installed (#522) - thanks @shawnlaffan
  • r2C and i2C now handle long double both real and complex (#524) - thanks @wlmb for report
  • add "update_data_from" method as streamlined get_dataref/upd_data
  • add Math::csqrt{,_up} (#524) - thanks @wlmb
  • Core::upd_data now sets DATACHANGED so will work for flowing ops
  • remove CopyBadStatusCode key from PP (#517)
  • badflag now not propagated back to inputs if set on outputs (#517)
  • add new_around_pointer (#505) - thanks @chrisarg for idea
  • add do_print to perldl to match pdl2
  • add {which,where}ND_both - thanks @guillepo for inspiration
  • add Core::tocomplex (#527) - thanks @wlmb for suggestion
  • add Math::c{log,acos,asin,acosh,atanh} (#527) - thanks @wlmb for suggestion
