The [[CVDMBF]] function decodes an 8-byte [[STRING]] generated by [[MKDMBF$]] (or read from a file) to [[DOUBLE]] numeric values.


{{PageSyntax}}
: {{Parameter|result#}} = [[CVDMBF]]({{Parameter|stringData$}})


{{PageDescription}}
* ''CV'' functions ([[CVD]], [[CVS]], [[CVI]], [[CVL]], [[CVDMBF]], [[CVSMBF]]) are used to convert values encoded by ''MK$'' functions ([[MKD$]], [[MKS$]], [[MKI$]], [[MKL$]], [[MKDMBF$]], [[MKSMBF$]]).
* '''QB64''' has [[_CV]] and [[_MK$]] functions which can also deal with extended [[Data types|data types]].
* [[DOUBLE]] values can range up to 15 decimal point digits. Decimal point accuracy depends on whole value places taken.


{{PageExamples}}
''Example 1:'' Showcases the reduced space to store an encoded number.
{{CodeStart}}
a# = 77000.24523213
{{Cl|PRINT}} "Value of a#:"; a#
b$ = {{Cl|MKDMBF$}}(a#)
{{Cl|PRINT}} "Value of a# encoded using MKDMBF$: "; b$
{{Cl|PRINT}} "The string above, decoded using CVDMBF:"; {{Cl|CVDMBF}}(b$)
{{CodeEnd}}
{{OutputStart}}
Value of a#: 77000.24523213

Value of a# encoded using MKDmbf$:  5─c▼d▬æ

The string above, decoded using CVDMBF: 77000.24523213
{{OutputEnd}}
:Since the representation of a double-precision number can use up to 15 ASCII characters (fifteen bytes), writing to a file using [[MKDMBF$]] conversion, and then reading back with the [[CVDMBF]] conversion can save up to 7 bytes of storage space.
