Trigonometric Instructions
(SIN, COS, TAN, ASN, ASIN, ACS, ACOS, ATN, ATAN)
The trigonometric instructions evaluate arithmetic operations by using
trigonometric operations.
You can mix data types, but loss of accuracy and rounding error might occur and
the instruction takes more time to execute. Check the overflow status bit (S:V) to
see whether the result was truncated.
For relay ladder instructions, bold data types indicate optimal data types. An
instruction executes faster and requires less memory if all the operands of the
instruction use the same optimal data type, typically DINT or REAL.
