Operand Data Areas
S: First source word
S R
R: First result word
When the execution condition OFF, ATAN(465) is not executed. When the
execution condition is ON, ATAN(465) computes the angle (in radians) for a tan-
gent expressed as the 32-floating-point content of S and S+1, and places the
result in R and R+1.
–1
S+1
TAN
R+1
The result is output to words R+1 and R as an angle (in radians) within the range
of –π/2 to π/2.
The tangent must be floating-point data within a range of –1.0 to 1.0.
Note Refer to page 115 for general precautions on operand data areas.
