DOUBLE
COSINE
COSD
@COSD
852
Calculates the cosine of the angle (radians) in the specified double-preci-
sion floating-point data (64 bits) and outputs the result to the result words.
Output
Required
DOUBLE TAN-
GENT
TAND
@TAND
853
Calculates the tangent of the angle (radians) in the specified double-preci-
sion floating-point data (64 bits) and outputs the result to the result words.
Output
Required
DOUBLE ARC
SINE
ASIND
@ASIND
854
Calculates the angle (in radians) from the sine value in the specified dou-
ble-precision floating-point data (64 bits) and outputs the result to the
result words. (The arc sine function is the inverse of the sine function; it
returns the angle that produces a given sine value between -1 and 1.)
Output
Required
DOUBLE ARC
COSINE
ACOSD
@ACOSD
855
Calculates the angle (in radians) from the cosine value in the specified
double-precision floating-point data (64 bits) and outputs the result to the
result words. (The arc cosine function is the inverse of the cosine function;
it returns the angle that produces a given cosine value between -1 and 1.)
Output
Required
DOUBLE ARC
TAN GENT
ATAND
@ATAND
856
Calculates the angle (in radians) from the tangent value in the specified
double-precision floating-point data (64 bits) and outputs the result to the
result words. (The arc tangent function is the inverse of the tangent func-
tion; it returns the angle that produces a given tangent value.)
Output
Required
DOUBLE
SQUARE ROOT
SQRTD
@SQRTD
857
Calculates the square root of the specified double-precision floating-point
data (64 bits) and outputs the result to the result words.
Output
Required
DOUBLE EXPO-
NENT
EXPD
@EXPD
858
Calculates the natural (base e) exponential of the specified double-preci-
sion floating-point data (64 bits) and outputs the result to the result words.
