octave: scripts/strings/dec2hex.m annotate

annotate scripts/strings/dec2hex.m @ 31848:1f3f7e874203

dec2base.m: Accept negative and fractional inputs (bug #63282) Previously only dec2bin and dec2hex accepted negative inputs but not dec2base, which led to inconsistency and repeated code. This changeset centralizes the negative input functionality in dec2base, and eliminates that code in the other functions. It also adds the ability to accept fractional inputs in dec2base. dec2base.m: Add new functionality to handle negative inputs and fractional inputs. Update BISTs. Add documentation. dec2bin.m: Remove code to handle negative inputs. Pass through to dec2base. Add code for padding the output to Matlab-compatible sizes. Update BISTs. Add documentation. dec2base.m: Remove a matrix indexing bug. Pass through to dec2bin. Update BISTs. Add documentation. NEWS.9.md: Add note about new functionality.
