Implement the arithmetic conversions in terms of resize_and_overwrite()

Reason: Performing the conversions without accessing private members, providing a model for users to implement their own with comparable efficiency.
Add a resize_and_overwrite() member

-# Generic Azure Pipelines build script for boostorg repositories
-# See: https://github.com/boostorg/boost-ci/
-#
-# Instructions for customizing this script for your library:
-#
-# 1. Customize the compilers and language levels you want.
-# 2. If you have more than include/, src/, test/, example/, examples/,
-#    benchmark/ or tools/ directories, set the environment variable DEPINST.
-#    For example if your build uses code in "bench/" and "fog/" directories:
-#      - DEPINST: --include bench --include fog
-# 3. Enable pull request builds in your boostorg/<library> account.
-#
-# That's it - the script will do everything else for you.

-# Generic Travis CI build script for boostorg repositories
-# See: https://github.com/boostorg/boost-ci
-#
-# Instructions for customizing this script for your library:
-#
-# 1. Customize the compilers and language levels you want in the 'jobs'.
-# 2. If you have more than include/, src/, test/, example/, examples/, or
-#    tools/ directories, modify your Travis CI project and add the environment
-#    variable DEPINST.  For example if your build uses code in "bench/" and
-#    "fog/" directories, then set DEPINST to the following:
-#        --include bench --include fog
-# 3. If you want to enable Coverity Scan, you need to provide the environment
-#    variables COVERITY_SCAN_TOKEN and COVERITY_SCAN_NOTIFICATION_EMAIL in
-#    your github settings.
-# 4. If you want to enable a big-endian build, you need to uncomment the
-#    big-endian build job.
-# 5. Enable pull request builds in your boostorg/<library> account.
-#
-# That's it - the scripts will do everything else for you.

Author	SHA1	Message	Date
Gennaro Prota	9c5d69475d	Implement the arithmetic conversions in terms of resize_and_overwrite() Reason: Performing the conversions without accessing private members, providing a model for users to implement their own with comparable efficiency.	2025-10-09 17:45:16 +02:00
Gennaro Prota	300781d954	Add a resize_and_overwrite() member Reason: This is in preparation of the next commit. See its commit message.	2025-10-09 17:45:16 +02:00
Gennaro Prota	cd1a1a41c3	Don't use an additional buffer in the arithmetic conversions In the case of the floating point conversions, this effectively avoids a copy of the buffer contents. In the case of the integer conversions, it doesn't eliminate the copy, but still removes the extra buffer. This fixes issue #65.	2025-10-09 17:45:16 +02:00
