❓ Float или Double?

Программисты часто не могут выбрать необходимую точность для чисел с плавающей запятой. Float требует всего 4 байта, но имеет только 7 значащих цифр, а Double в два раза точнее (15 цифр), но в два раза прожорливее.

🗣️ Фактически, большинство процессоров могут одинаково эффективно работать как с Float, так и с Double, поэтому воспользуйтесь рекомендацией Бьорна Страуструпа (автор языка С++):

Выбор правильной точности для решения реальных задач требует хорошего понимания природы машинных вычислений. Если у вас его нет, либо посоветуйтесь с кем-нибудь, либо изучите проблему самостоятельно, либо используйте Double и надейтесь на лучшее.

Telegram Desktop App Not Working on Windows?

Access Telegram With a VPN

If running the app in compatibility mode does not work, try accessing the app through a VPN. Sometimes, certain apps and services are unavailable in specific locations, or a person's IP address is banned by Telegram due to long hours of usage. It is also possible that the app itself is blocked in certain countries. Hence, you should try connecting the app via a VPN to eliminate this possibility. If you're already using a VPN and the app isn't working correctly, try changing your IP and location on the VPN first and, when that doesn't help, consider temporarily disabling it.

Telegram Q&A
Q: How does hottg.com work?
Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

Q: What is Telegram? What do I do here?

Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.

Q: Who is Telegram for?

Telegram is for everyone who wants fast and reliable messaging and calls. Business users and small teams may like the large groups, usernames, desktop apps and powerful file sharing options. You can appoint admins with advanced tools to help these communities prosper in peace. Public groups can be joined by anyone and are powerful platforms for discussions and collecting feedback.In case you're more into pictures, Telegram has animated gif search, a state of the art photo editor, and an open sticker platform (find some cool stickers here or here). What's more, there is no need to worry about disk space on your device. With Telegram's cloud support and cache management options, Telegram can take up nearly zero space on your phone.

Q: How is Telegram different from WhatsApp?

Unlike WhatsApp, Telegram is a cloud-based messenger with seamless sync. As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each. And if you don't want to store all that data on your device, you can always keep it in the cloud.Thanks to our multi-data center infrastructure and encryption, Telegram is faster and way more secure. On top of that, Telegram is free and will stay free — no ads, no subscription fees, forever.

Q: Can I make calls via Telegram?

Yes! Voice calls are currently available to users around the world.
