↑COS(461)
Operand Data Areas
S: First source word CIO, G, A, T, C, #, DM
R: First result word CIO, G, A, DM
When the execution condition OFF, COS(461) is not executed. When the execu-
tion condition is ON, COS(461) computes the cosine of the angle (in radians)
expressed as the 32-floating-point content of S and S+1, and places the result in
R and R+1.
R+1 R
S Source (floating-point data, 32 bits)
S+1
Result (cosine value, floating-point
data, 32 bits)
COS
Specify the angle in radians for S and S+1. For information on converting from
degrees to radian, refer to
5-21-9 DEGREES-TO-RADIANS: RAD(458)
.
Relation Between Input Data and Result
S: Angle (radian) data
R: Result (cosine)
R
Precautions S and S+1must be floating-point data and its absolute value must be less than
65,536.
Note Refer to page 115 for general precautions on operand data areas.
Flags ER (A50003): The absolute value of S and S+1is 65,536 or greater.
S and S+1is not floating-point data.
The content of a*DM word is not BCD when set for BCD.
EQ (A50006): The exponent and mantissa of the result are 0.
N (A50008): The result is a negative number.
OF (A50009): OFF when the computation is executed.
UF (A50010): OFF when the computation is executed.
