Powerful and lightweight command line calculator.
Run tmsolve --help (or tmsolve.exe --help for Windows) to see supported command line arguments.
The calculator has the following modes:
- Scientific (S) (default)
- Integer (I)
- Function (F)
- Equation (E)
- Utility (U)
To switch between modes, add the correct letter after the command mode
Example: mode I will switch to integer mode.
priority: high to low, groups in [] have the same priority:
() ^ [ * / % ] [ + - ]
Where:
^ Power operator.
* / % Multiplication, division, modulo.
+ - Addition and subtraction.
Provided by libtmsolve, check them here.
- Supports user defined functions and variables.
- Supports hexadecimal, octal and binary represenation using prefixes
0x,0o,0bor functionshex(),oct(),bin(). - "ans" variable stores previous results.
- Supports complex numbers.
- Does not allow implied multiplication except for the imaginary "i" with numbers, where for example 5i is treated as (5*i).
- Attempts to find the reduced fractional form of the result.

Uses only integers and supports bitwise operations.
priority: high to low, groups in [] have the same priority:
() [ * / % ] [ + - ] & ^ |
Where:
* / % Multiplication, division and modulo.
+ - Addition and subtraction.
& Bitwise AND.
^ Bitwise XOR.
| Bitwise OR.

By default, this mode uses 32 bit signed integers, but can be changed to 8, 16, 32, or 64 bits of width during runtime using the command set and width specifier w1, w2, w4, w8.

Calculates a function over the specified interval. example: Calculating points across a parabola:
Current mode: Function
f(x) = x^2
Start: -4
-4
End: 4
4
Step: 1
1
f(-4) = 16
f(-3) = 9
f(-2) = 4
f(-1) = 1
f(0) = 0
f(1) = 1
f(2) = 4
f(3) = 9
f(4) = 16
You can use the prev keyword to get the last used function.
Used to solve simple equations up to and including third order.
Current mode: Equation
Degree? (n<=3)

a*x^3 + b*x^2 + c*x + d = 0
a = 1
b = 7
c = 16
d = 12
Equation: 1 x^3 + 7 x^2 + 16 x + 12 = 0
Solutions:
x1 = -3
x2 = x3 = -2
Degree? (n<=3)

c = -1
Equation: 4 x^2 - 3 x - 1 = 0
Solutions:
x1 = -0.25
x2 = 1
