Double-precision Floating-point Instructions (CS1-H, CJ1-H, CJ1M, or CS1D Only)
Section 3-16
Flags
Precautions
The Multiplicand (Md to Md+3) and Multiplier (Mr to Mr+3) data must be in
IEEE754 floating-point data format.
3-16-8 DOUBLE FLOATING-POINT DIVIDE: /D(848)
Purpose
Divides one double-precision (64-bit) floating-point number by another and
places the result in the specified destination words.
This instruction is supported by CS1-H, CJ1-H, CJ1M, and CS1D CPU Units
only.

Error Flag
ER
ON if the multiplicand or multiplier data is not recognized
as floating-point data.
ON if the multiplicand or multiplier is not a number (NaN).
ON if +
∞
and 0 are multiplied.
ON if –
∞
and 0 are multiplied.
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 floating-point value.
Underflow Flag
UF
ON if the absolute value of the result is too small to be
expressed as a double-precision floating-point value.
Negative Flag
N
ON if the result is negative.
OFF in all other cases.
