This topic explains all the advanced features of the Hot Calculator.
Your mathematical expressions may contain integer numbers as well as real numbers in both scientific notation and floating point notation.
You can use the following decimal separators for the real numbers: the Point, the Comma, or another decimal separator specified in the Regional settings of Windows.
An expression can contain text in any case (lowercase and uppercase characters are equivalent).
Your expressions may be as long and as complex as necessary. The Hot Calculator has not such limitations.
But the Hot Calculator has the only limitation regarding the expression length. The Hot Calculator is able to properly detect expressions for calculating which are not longer than 32 characters.
The following arithmetic operators can be used within the expression for calculating.
Operator | Operation | Example |
+ | Addition | 12.5+256 |
- | Subtraction | 112-7e6 |
* or · (symbol with code 183) | Multiplication | 5*65 2·4 |
/ or : | Division | 10/3 7.5:8 |
^ | Raising to power | 2^8 |
The following postfix operators are allowed.
Operator | Operation | Example |
! | Factorial | 22! |
% | Percents (can be used in conjunction with another arithmetical operator from the above table) |
12+40% 1000-20% 77*24% 65/17.5% |
In most situations you can do not specify the multiplication operator (to skip it).
So the following expressions are valid.
8Pi
-4.47sin(2)
2.56(2+3.5)
lg(67)12e-2
cos(pi/2)pi
exp(6)ctg(pi/2)
arccos(1)(3+7.45)
(2+2)77
(56+3.5)pi
(2+3.5)arcsin(1)
(17E5+pi)(4+5e)
Your expressions can contain the following predefined constants.
Constant | Description | Example |
Pi | The ratio of a circle's circumference to its diameter 3.1415926535897932385 |
2Pi^2 |
e | The base of the natural logarithms 2.7182818285 |
Ln(e) |
Atlantis allows you to use about 90 predefined functions.
You can quickly insert the desired predefined function to the active document by clicking the Insert function toolbar button or pressing the Ctrl+Alt+= keys.
Note that you can select some text in the document before inserting a function to enclose this text with the brackets of the function being inserted.

The following table contains information about the order in which different elements of expressions are calculated (the elements with the highest priority are calculated first).
Priority | Element of Expression |
1st (highest) | Subexpression enclosed within the brackets |
2nd | Predefined Function |
3rd | Postfix Operators (Factorial, Percents) |
4th | The Power Operator (^) |
5th | Multiplication and Division Operators |
6th (lowest) | Addition and Subtraction Operators |
