Program Example
10 ' Converts an integer or a single precision real number into a double precision real number
20 A%=256
:
' Defines an integer
30 B!=5.78
:
' Defines a single precision real number
40 A#=CDBL(A%)
:
' Converts an integer to a double precision
real number
50 B#=CDBL(B!)
:
' Converts a single precision real number to
a double precision real number
60 PRINT "A%=";A%,"B!=";B!
:
' Value before conversion
70 PRINT "A#=";A#,"B#=";B#
:
' Value after conversion
80 END
RUN
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.
