Description
DBLL(844) converts the 32-bit signed binary value in S+1 and S to double-
precision (64-bit) floating-point data (IEEE754-format) and places the result in
words D to D+3. A single 0 is added after the decimal point in the floating-
point result.
Signed binary data within the range of –2,147,483,648 to 2,147,483,647 can
be specified for S+1 and S. The floating point value has 24 significant binary
digits (bits). The result will not be exact if a number greater than 16,777,215
(the maximum value that can be expressed in 24-bits) is converted by
DBLL(844).
Example Conversions:
A signed binary value of 16,777,215 is converted to 16,777,215.0.
A signed binary value of –16,777,215 is converted to –15,777,215.0.
