Algebric bot

The bot will help you calculate an algebraic expression both in chat and in inline mode. For more information, see /help

You can calculate the result of an algebraic expression. You can use brackets, floating-point numbers (decimal separator - "." (dot)). +, -, *, /, ^ (exponentiation), functions of sine (sin), cosine (cos), tanges (tan), modulus of number (abs), square root (sqrt), squaring (sqr).
Example: sqr(212.5-4).
The bot supports inline mode.
If you add a symbol or currency designation at the end, the bot will additionally convert the result, for example, to the query 100 + 7 euro to dollar, the bot will calculate the expression (107 euro) and output the result in dollars at the current exchange rate. The bot also supports the calculation of the cryptocurrency exchange rate: bitcoins, ethereum, toncoin, etc.
In online mode, you can interactively select the currency to convert.
The bot can work in groups if it has access to messages. In this case, the bot will consider all algebraic expressions by analogy, but in this case you need to add the '=' sign at the beginning. For example, = 3452-45 $ .
You can use your own set of variables using the /set command. For example, /set balance 500 will set the balance variable to 500. In subsequent calculations, the use of the balance variable in formulas will automatically use the value 500. You can also do operations with a variable, for example, /set balance +100 will increase the value of the stored variable by 100
