Additional Information
• Use the RadToDeg and DegToRad instructions (page 2-172) to convert between degrees and radi-
ans.
• If In for the TAN instruction is nπ/2, when n is an integer, then the value of Out will be positive or neg-
ative infinity. Use the CheckReal instruction (page 2-209) to see if the value of Out is positive infinity
or negative infinity.
Precautions for Correct Use
• If the value of In is positive infinity, negative infinity, or nonnumeric data, the value of Out is nonnu-
meric data.
• If you pass an integer parameter to In, the data type is converted as follows:
Data type of parameter that is
passed to In
USINT, UINT, SINT, or INT
UDINT or DINT
ULINT or LINT
