On VFP9:
*CVD()
* correct
CTOBIN(8bytes,"BRS")
* uses
CTOBIN(8bytes,"BS")
I hope this bug will be fixed on SP2.
* CVS and CVD
CTOBIN(4or8bytes,"NRS")
Remember, VFP doesn't support 32bit floating point (single),
then the conversion to double can add a rounding error.

example
* double
? CTOBIN(0H+BINTOC(0.1E0,"BRS"),"NRS")

* single
? CTOBIN(0H+BINTOC(0.1E0,"fRS"),"NRS")
