## S4 method for signature 
## 'PiecewiseLinearFuzzyNumber,PiecewiseLinearFuzzyNumber'
arctan2(y, x)

Arguments

y

a PiecewiseLinearFuzzyNumber

x

a PiecewiseLinearFuzzyNumber

Details

Note that resulting values are no longer from interval [-pi,pi] but [-1.5pi,pi], in order to provide valid fuzzy numbers as result.

Value

Returns a fuzzy number of the class PiecewiseLinearFuzzyNumber indicating the angle specified by the input fuzzy numbers. The range of results is [-1.5pi,pi].
