Features
Amazing support for Sigma and Pi
This is a fantastic feature of this calculator that it is capable of evaluating expressions containing Sigma and Pi.
Passing Sigma(1,100,n) will evaluate to 5050 as n is summationed from 1 to 100.
and Pi(1,15,n) will evaluate to 1307674368000 as n is multiplied from 1 to 15 which is equal to 15!
Parenthesis less expression
If a expression is readable by human then it is readable by this evaluator. There is no need to wrap every function inside parenthesis. For eg. sin90 will work totally fine instead of sin(90)
##Changelog
Removed lodash.indexof and used native Array.prototype.indexOf hence dropping suppports for IE8 and below.
This will reflect in next release named v1.2.16
