Operation:
Converts a floating point value at S into separate
mantissa and exponent parts at D and D
+1
(scientific format).
Points to note:
a) The instruction must be double word format. The destinations D and D
+1 represent the
mantissa and exponent of the floating point number respectively.
b) To provide maximum accuracy in the conversion the mantissa D will be in the range 1000 to
9999 (or 0) and the exponent D
+1 corrected to an appropriate value.
c) E.g. S= 3.4567 × 10
-5
will become D= 3456, D+1 =-8
