Is there a way to convert a Float to 32 bits/4 bytes and back again?

oh yeah...
Those things explode after some period of time and they are completely useless as soon as something new arives. >:(

I'm certain I'm not diving into the base of some device or sensor if there are library's available.
I get a float sized number and I'll try to stick that into my EEPROM.
Some help is appriciated. But there is no need to learn the French language if I'm only in France for the holydays.
