Description
The best calculator app for Android!
- Multiple workspaces with their own history and variables. - History and variables are automatically saved and restored. - Evaluates math expressions including grouping. - Supports trigonometry and other functions. - Converts units of distance, speed, temperature, time, volume, and mass.
Create multiple workspaces with their own history and variables that are saved when the application exits. Enter simple or complex mathematical expressions and immediately calculate the result. From adding your grocery bill to calculating cosine to doing your taxes, Calculate X does it all. Use the special variable `answer` to refer to the most recent result. Tap a previous entry to copy it to the input field. Results are automatically added to a history record, so you don't have to write them down to remember them. Those results are even saved and restored when you exit and restart the application.
There is also a Windows version on the Microsoft Store.
Basic Mathematical Operators
Calculate X supports the basic mathematical operators: addition, subtraction, multiplication, division, modulo, and exponent. You can use parentheses to group expressions and give them precedence.
You can also use algebraic (implied) multiplication in many cases:
Between groups: (3 + 4)(5 - 2) Before and after groups: -17(9 / 3)42 Before and after functions: 23sqrt(9)ceiling(25 / 2)12 Between groups and functions: (4 + 3)sqrt(9)(12 / 2) Between groups and variables: (4 + 3)e(12 / 2) Before variables: 4pi
Variables
You can create variables and access them in your expressions. Variables can contain letters, digits, and underscores, but they must start with a letter. All variables and their current values are displayed in the list on the right.
Examples:
x = 23.68 y2 = sqrt(146) x2y = x * y2 result = 12 + 8.4 subtotal3 = result - x2y + 87 The 'pi' and 'e' variables are pre-defined. The 'answer' variable always equals the most recent result.
Examples:
y = sin(pi / 2) y2 = asin(2pi) x = y + 2 x + 1 (The result is 4 and the answer variable is automatically set to 4.)
You can clear a variable (and remove it from the variables list) by setting it to nothing.
