S1: Comparison data 1
S2: Comparison data 2
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-
S
tion; it returns the angle that produces a given tangent value.)
R
Calculates the square root of the specified double-precision floating-point
data (64 bits) and outputs the result to the result words.
S
R
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.
S
R
Calculates the natural (base e) logarithm of the specified double-precision
floating-point data (64 bits) and outputs the result to the result words.
S
R
Raises a double-precision floating-point number (64 bits) to the power of
another double-precision floating-point number and outputs the result to
the result words.
B
E
R
Compares the specified double-precision data (64 bits) and creates an ON
execution condition if the comparison result is true.
Three kinds of symbols can be used with the floating-point symbol com-
parison instructions: LD (Load), AND, and OR.
