Replicalc

Replicalc is a lightweight, keyboard-driven calculator. Expressions are evaluated inside a REPL, similar to the classic TI-83 calculator.

Replicalc supports Linux and Windows. The BSDs and MacOS should also work, but are untested. Windows binaries are provided under Releases.

Usage

To evaluate an expression, type it into the prompt:

> 9 * 3
27

The result is automatically stored inside the ans variable. This can be used in further expressions:

> 9 * 3
27

> ans
27

> ans + 4
31

Results can be stored inside an alternative variable using the assignment operator (=):

> foo = 10
foo = 10

Use the vars command to print a list of variables and their respective values:

> vars
Variables:
 ans  31
 foo  10

Fractions are supported, up to four decimal places. The decimal places are automatically omitted for whole numbers:

> 9 / 3
3

> 9 / 3.0001
2.9999
