The CVSMBF function decodes a 4-byte STRING generated by MKSMBF$ (or read from a file) to SINGLE numeric values.
Syntax
- result! = CVSMBF(stringData$)
Description
- CV functions (CVD, CVS, CVI, CVL, CVDMBF, CVSMBF) are used to convert values encoded by MK$ functions (MKD$, MKS$, MKI$, MKL$, MKDMBF$, MKSMBF$).
- QB64 has _CV and _MK$ functions which can also deal with extended data types.
- SINGLE values can range up to 7 decimal point digits. Decimal point accuracy depends on whole value places taken.
Examples
Example 1: 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:"; CVSMBF(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.
