Ignore NA in math

Description

Simplifying math functions are simple wrappers of math function (- +). If any of the left-hand side or right-hand side is NA, Inf or NaN it returns any rational value, if there is any.

However, if the both values are irrational it returns NA. The result is then passed to the corresponding math function.

Usage

.x %minus_% .y

.x %plus_% .y
