Important Notice
The pages on this site contain documentation for very old MS-DOS software,
purely for historical purposes.
If you're looking for up-to-date documentation, particularly for programming,
you should not rely on the information found here, as it will be woefully
out of date.
MKSMBF$, MKDMBF$, CVSMBF, CVDMBF Functions
◄Contents► ◄Index► ◄Back►
──────────────────────────────────────────────────────────────────────────────
MKSMBF$ and MKDMBF$ convert IEEE-format numbers to Microsoft-Binary-format
numeric strings that can be stored in FIELD statement string variables.
CVSMBF and CVDMBF convert those strings back to IEEE-format numbers.
MKSMBF$(single-precision-expression!)
MKDMBF$(double-precision-expression#)
CVSMBF (4-byte-numeric-string)
CVDMBF (8-byte-numeric-string)
Function Returns
════════ ════════════════════════════════════════════════════════════
MKSMBF$ A 4-byte string containing a Microsoft-Binary-format number
MKDMBF$ An 8-byte string containing a Microsoft-Binary-format number
CVSMBF A single-precision number in IEEE format
CVDMBF A double-precision number in IEEE format
■ These functions are useful for maintaining data files created with
older versions of Basic.
Example:
TYPE Buffer
SngNum AS STRING * 4
DblNum AS STRING * 8
END TYPE
DIM RecBuffer AS Buffer
OPEN "TESTDAT.DAT" FOR RANDOM AS #1 LEN = 12
SNum = 98.9
DNum = 645.3235622#
RecBuffer.SngNum = MKSMBF$(SNum)
RecBuffer.DblNum = MKDMBF$(DNum)
PUT #1, 1, RecBuffer
GET #1, 1, RecBuffer
CLOSE #1
PRINT CVSMBF(RecBuffer.SngNum), CVDMBF(RecBuffer.DblNum)
