float and double internal representation

i want to know in which format floats/doubles are stored in memory( formats like IEEE eg …, are there others ?) and how to convert between them, or generate them by myself and i want to know hoch the precisions of float and double are.

well you own something like VC++ do you ??
go to the help and search for “float” or “data types”
if this doesn’t help drop me a mail and I send you some infos. I’m just too lazy now ))
