```{index} single: howbig; PDL::Core function ``` ```{index} single: PDL::Core::howbig; Perl function ``` # howbig `howbig($typecode)` — size in bytes of a PDL type, by integer type code. Mirrors upstream `PDL::Core::howbig` (PP-generated from `Core.pd`: `pp_def('howbig', GenericTypes => \@all, Pars => 'int a(); int [o]b();', ...)`). Free function, callable as `PDL::Core::howbig(10)` and re-exported via `*PDL::howbig`. `PDL::Types.pm:556` also calls this to back the `$type->howbig` method.
