scanfp (c).SVD.,2001,2021

Download: scanfp v.0.000a (50kb size, PKLited & UPX'ed)

- simple command line tool for converting floating point numbers between BIN<->STR representation.

This program converts the entered floating point number into its binary representation as "DB" assembly code.

And vice versa - the binary representation of a number from a file is output as its "DD / DQ / DT" representation as an assembler string.

The program works with three types of floating point numbers
- DD - float (32bit)
- DQ - double (64bit)
- DT - long double (80bit FPU)

This program works in pure DOS and in WIN_ALL (DUAL WIN32 PE-EXE).

DOS16-stub created 2001 using TurboC v.2.0
WIN32-cmd crated 2021 using BorlandC v.5.1.


Usage: C>scanfp [f|d|l]  <input  >output
                f = scanf("%e" ,...) - float  32bit
                d = scanf("%le",...) - double 64bit
                l = scanf("%Le",...) - fpu    80bit - default!

or:    C>scanfp p [f|d|l] inpFile
                f = printf("%e" ,...) - float  32bit
                d = printf("%le",...) - double 64bit
                l = printf("%Le",...) - fpu    80bit - default!

For example:

String to DB code ->

C> scanfp       
C> scanfp f
C> scanfp d

BINfile to DD/DQ/DT+DB code ->

C> scanfp p InputFile
C> scanfp p f InputFile
C> scanfp p d InputFile

Sample of output:


C> scanfp  <stdin

db 000h,000h,000h,0A0h,06Fh,0B5h,0A4h,0B3h,02Ah,040h ;;=+1.23450000000000000000e+13

C> scanfp d  <stdin

C> scanfp f  <stdin

C> scanfp p f 32

dd +1.2000000e-08              ;;=db 08Fh,028h,04Eh,032h
