Haskalc

NAME

haskalc - a calculator written in the Haskell programming language

SYNOPSIS

DESCRIPTION

haskalc is a simple calculator written in the Haskell programming language.

USAGE

The calculator currently supports integers and floating-point numbers and these basic operators:

+ (addition)
- (subtraction)
* (multiplication)
/ (division)
% (modulo)
^ (exponentiation)
< (less than)
> (greater than)
= (assignment)

Usage:

x = 10 (variable)
f(x) = 2 * x (function)

Note: built-in variables and function cannot be overwritten.

?: (conditional)

Usage:

condition ? true_case : false_case

To exit the calculator write exit or send an EOF-character with Ctrl+D.
