Double-precision Floating-point Instructions (CS1-H, CJ1-H, CJ1M, or CS1D Only)
Section 3-16
Precautions
The content of words S to S+3 must be floating-point data and the integer por-
tion must be in the range of –2,147,483,648 to 2,147,483,647.
3-16-3 16-BIT TO DOUBLE FLOATING: DBL(843)
Purpose

point data and places the result in the specified destination words.
This instruction is supported by CS1-H, CJ1-H, CJ1M, and CS1D CPU Units
only.
