Calculator: the bot computes by a formula and remembers the result

The bot takes your formula, plugs in values gathered earlier (a price and a quantity, say) and computes the result. The calculation runs on the server — the person doesn't see it, they only get the finished figure where you choose to show it. The bot remembers the result in a "cell" (a variable) to insert into a message or use later.

Formula

The calculation itself — for example {{price}} * {{qty}} * 0.9 (price × quantity with a 10% discount). You can use numbers, the signs + − * /, brackets and the functions round, floor, ceil, abs, min, max. Up to 500 characters.

Result variable

The name of the "cell" to put the result into — for example total. Latin letters, no spaces, not starting with a digit.

Where to store the result

Remember the result only within this conversation or attach it to the person permanently. Only within this conversation by default.

Decimal places

How many digits to keep after the decimal point: 2 for money (500.00), 0 for a whole number. From 0 to 8, 2 by default.

The customer chose 3 coffees at 80 UAH. The "Calculator" block computes {{price}} * {{qty}} * 0.9 as 216.00 and puts the result into the variable total. Next the bot issues an invoice for that amount with the "Payment" block.
