Function
DOUBLE SINE SIND @SIND 851
Calculates the sine of a double-precision (64-bit)
floating-point number (in radians) and places the
result in the specified destination words.
DOUBLE COSINE COSD @COSD 852
Calculates the cosine of a double-precision (64-
bit) floating-point number (in radians) and places
the result in the specified destination words.
DOUBLE TANGENT TAND @TAND 853
Calculates the tangent of a double-precision (64-
bit) floating-point number (in radians) and places
the result in the specified destination words.

Error Flag P_ER • ON if the source data is not recognized as floating-point data.
• ON if the source data is not a number (NaN).
• ON if the absolute value of the source data exceeds 65,535.
• OFF in all other cases.
Equals Flag P_EQ • ON if both the exponent and mantissa of the result are 0.
• OFF in all other cases.
Overflow Flag P_OF • SIND, COSD
Unchanged
•TAND
•ON if the absolute value of the result is too large to be expressed as a double-precision (64-bit) float-
ing-point value.
•OFF in all other cases.
Underflow Flag P_UF Unchanged
Negative Flag P_N • ON if the result is negative.
• OFF in all other cases.
