10 ' Converts an integer or a single precision real number into a double precision real number
20 A%=256
30 B!=5.78
40 A#=CDBL(A%)
50 B#=CDBL(B!)
60 PRINT "A%=";A%,"B!=";B!
70 PRINT "A#=";A#,"B#=";B#
80 END

A%= 256
B!= 5.78
A#= 256
B#= 5.779999732971191
OK

REMARK
• The value is automatically converted to a double precision real number when a
value is assigned to a double precision variable, or when a double precision real
value is used as part of an arithmetic calculation. Therefore, A#=CDBL(3042.12!)
and A#=3042.12! have the same result.
