Processing details
■Operation processing
• These functions calculate the tangent of the REAL data type value (angle) input to (s), and output the operation result from
(d).
• When the input value is defined as A and the output value is defined as B, the relationship of A and B will be as follows:
B=TAN A
• Note that even if the input value is π/2 radian or (3/2)π radian, no error will be issued because of the truncation error in the
radian value.
• Input a REAL data type value to (s). Input a value (angle) in radians (angle×π/180).
■Operation result
The operation processing is performed. The operation result is output from (d).
