Double-precision Floating-point Instructions (CS1-H, CJ1-H, CJ1M, or CS1D Only)
Section 3-16
Flags
Precautions
The source data in words S to S+3 must be in IEEE754 floating-point data for-
mat.
3-16-14 DOUBLE ARC SINE: ASIND(854)
Purpose
Calculates the arc sine of a double-precision (64-bit) floating-point number
and places the result in the specified destination words. (The arc sine function
is the inverse of the sine function; it returns the angle that produces a given
sine value between –1 and 1.)
This instruction is supported by CS1-H, CJ1-H, CJ1M, and CS1D CPU Units
only.

Error Flag
ER
ON if the source data is not a number (NaN).
ON if the absolute value of the source data exceeds
65,535.
OFF in all other cases.
Equals Flag
=
ON if both the exponent and mantissa of the result are 0.
OFF in all other cases.
Overflow Flag
OF
ON if the absolute value of the result is too large to be
expressed as a double-precision (64-bit) floating-point
value.
Underflow Flag
UF
Unchanged
Negative Flag
N
ON if the result is negative.
OFF in all other cases.
