ER: Indirectly addressed EM/DM word is non-existent.
(Content of *EM/*DM word is not BCD, or the EM/DM area boundary
has been exceeded.)
ON if the source data is not recognized as floating-point data.
EQ: ON if both the exponent and mantissa of the result are 0.
OF: ON if the absolute value of the result is too large to be expressed as a
32-bit floating-point value. (The result will be output as ±∞ .)
UF: ON if the absolute value of the result is too small to be expressed as a
32-bit floating-point value. (The result will be output as 0.)

The source data in S+1 and S must be in IEEE754 floating-point data format.
DM 6143 to DM 6655 cannot be used for R.
When the execution condition is OFF, SIN(––) is not executed. When the exe-
cution condition is ON, SIN(––) calculates the sine of the angle (in radians)
expressed as a 32-bit floating-point value in S+1 and S and places the result
in R+1 and R. (The floating point source data must be in IEEE754 format.)

SIN

S+1
R+1
Specify the desired angle (–65,535 to 65,535) in radians in S+1 and S. If the
absolute value of the angle exceeds 65,535, an error will occur and the
instruction won't be executed. For information on converting from degrees to
radians, see 5-24-9 DEGREES TO RADIANS: RAD(––).
The following diagram shows the relationship between the angle and result.
