4.6.6 ARC TANGENT (ATN)
J
Overview
The ATN command returns the arc tangent of integer or real number data as the operation re-
sult. Double integer data cannot be used.

The input units and output results are different for in teger and real number data.
D Integer Data
Integer data can be used within a range of −327.68 to 327.67 degrees. The immediately
preceding operation result (integer data) is used as the input, and the operation result is
returned in an integer register (input unit 1 = 0.01 degrees). The operation result is multi-
plied by 100 before being output.
D Real Number Data
The command uses the immediately preceding operation result (real number data) as in-
put, and returns the arc tangent in a real number register.
