Added a calculator interface along with an abstract calculator to facilitate a concrete calculator class.
Included by default are two calculators;
SimpleCalculator
andBinaryCalculator
.The
SimpleCalculator
uses the native PHPround
function in conjunction with the basic mathematical operators (+
,-
,*
,/
,%
), and thepow
function for power.The
BinaryCalculator
uses thebcmath
library, thus adding a requirement for this component for thebcmath
extension.See #12 for original issue details.
