ATAN - Arc Tangent
Instruction Type: Output
Use the ATAN instruction to take the arc tangent of a number (source) and
store the result (in radians) in the destination. Address Levels for the operands
involved in the ATAN can be ALL word, ALL Long word, ALL float, or a
combination. These operands shall undergo a conversion to float. The
calculation of the source (in float) is then performed, and the result is then cast
to the data type of Destination.
Destination data always greater than or equal to -
π
/2, and less than or equal to
π
/2.
