>Hi All,

>Has anyone previously read 32 bit floats from disk? I'm importing information from a disk file that contains Character and numeric information. The character info is no problem and I can convert 16 bit Ints easily. However, floats are stored in a totally different format. Has anyone cracked this before?

This converts VFP's B format, which is 64-bit float. Tweaking it you can get the 32 bit version:

Function bton
*+ douBle string --> numeric
* takes a 8 byte string with IEEE representation of a long real
* structure:
* 7. byte:  7 bit sign
*	6-0 bit exponent upper
* 6. byte, bits 7-4 exponent lower. Exponent has 0x400 added
*    bits 3-0 mantissa. Mantissa is normalised, ie. assume 1 for first bit
* bytes 5-0 rest of mantissa
* returns a number.

Dime bajt(8)
For j=1 to 8
	bajt[j]=asc(subs(_s,j))
Endf
znak=iif(bittest(bajt[8], 7), -1, 1)
eksp=bitand(bajt[8],127)*16+bitrshift(bajt[7], 4)
*eksp=bitand(eksp+1025, 1023)
eksp=eksp-1023
mant=1+bitand(bajt[7], 15)/16
dv=4096
For j=6 to 1 step -1
	mant=mant +bajt(j)/dv
	dv=dv*256
Endf
rez=mant*2**eksp*znak
