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.
Code:
Usage: C>scanfp [f|d|l] <input >output
where:
f = scanf("%e" ,...) - float 32bit
d = scanf("%le",...) - double 64bit
l = scanf("%Le",...) - fpu 80bit - default!
or: C>scanfp p [f|d|l] inpFile
where:
f = printf("%e" ,...) - float 32bit
d = printf("%le",...) - double 64bit
l = printf("%Le",...) - fpu 80bit - default!
For example:
Code:
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:
Code:
C> scanfp <stdin
db 000h,000h,000h,0A0h,06Fh,0B5h,0A4h,0B3h,02Ah,040h ;;=+1.23450000000000000000e+13
C> scanfp d <stdin
