Function
DBL
DBL(843) converts the 16-bit signed binary value in 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.
Only values within the range of -32,768 to 32,767 can be specified for S. To convert signed binary data
outside of that range, use DBLL(844).
Example conversions:
A signed binary value of 3 is converted to 3.0.
A signed binary value of -3 is converted to -3.0.
DBLL
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.
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.
