Function
îš„ SIND
SIND(851) calculates the sine of the angle (in radians) expressed as a double-precision (64-bit)
floating-point value in words S to S+3 and places the result in words D to D+3.
(The floating point source data must be in IEEE754 format.)
• Specify the desired angle (-65,535 to 65,535) in radians in words S to S+3.
For information on converting between degrees and radians, see 3-16-9 DOUBLE DEGREES TO
RADIANS: RADD(849) or 3-16-10 DOUBLE RADIANS TO DEGREES: DEGD(850).
• If the angle is outside of the range -65,535 to 65,535, an error will occur and the instruction will not be
executed.
z The following diagram shows the relationship between the angle and result.
îš„ COSD
COSD(852) calculates the cosine of the angle (in radians) expressed as a double-precision (64-bit)
floating-point value in words S to S+3 and places the result in words D to D+3.
(The floating point source data must be in IEEE754 format.)
• Specify the desired angle (-65,535 to 65,535) in radians in words S to S+3.
For information on converting between degrees and radians, see 3-16-9 DOUBLE DEGREES TO
RADIANS: RADD(849) or 3-16-10 DOUBLE RADIANS TO DEGREES: DEGD(850).
• If the angle is outside of the range -65,535 to 65,535, an error will occur and the instruction will not be
executed.
z The following diagram shows the relationship between the angle and result.
îš„ TAND
TAND(853) calculates the tangent of the angle (in radians) expressed as a double-precision (64-bit)
floating-point value in words S to S+3 and places the result in words D to D+3.
(The floating point source data must be in IEEE754 format.)
