Operand Specifications
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.
Converts a 16-bit signed binary value to double-precision (64-bit) floating-
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.
