Description

The ATN2() function returns the angle size, in radians, for the specified cosine and sine values of a given point. <expN1> and <expN2> represent the cosine and sine values, respectively. The angle size is returned as a numeric in radians. The SET DECIMALS command determines the number of decimals displayed in the returned angle size.

Example

set decimals to 4
?atn2(0.5000,0.8660)
