An R6RS Scheme Infix Arithmetic Calculator

R6RS Infix Calculator

Description

An R6RS Scheme Infix Arithmetic Calculator. Supports +, -, **, *, %, ( and ), and works with floating point numbers. To set the output as Decimal, uncomment the necessary line in the file. Exercise caution when using Decimal output, as Scheme has infinite precision. It should work with all R6RS Scheme Implementations, and has been tested with Chez and Guile Scheme

Usage

For Chez, append at the top of the file:

#!/usr/bin/chez --script

For Guile, append at the top of the file:

#!/usr/bin/guile -s
!#

For other R6RS compliant scheme implementations, check the ‘script’ header for your implementation and add it to the top of this file. To evaluate an expression, do:

./infix.scm "<expression>"
