QB64 is a modern extended BASIC programming language that retains QBasic/QuickBASIC 4.5 compatibility and compiles native binaries for Windows, Linux, and macOS.

The CVDMBF function decodes a 4-byte STRING generated by MKSMBF$ (or read from a file) to SINGLE numeric values.


result! = CVSMBF(stringData$)



Showcases the reduced space to store an encoded number.

a! = 700.2213
PRINT "Value of a!:"; a!
b$ = MKSMBF$(a!)
PRINT "Value of a! encoded using MKSMBF$: "; b$
PRINT "The string above, decoded using CVSMBF:"; CVDMBF(b$)

Value of a!: 700.2213
Value of a# encoded using MKSMBF$: *♫/è
The string above, decoded using CVSMBF: 700.2213

Since the representation of a double-precision number can use up to 7 ASCII characters (seven bytes), writing to a file using MKSMBF$ conversion, and then reading back with the CVSMBF conversion can save up to 3 bytes of storage space.
