ELI5: What happens when a country (like Egypt today) 'floats' it's currency?

Allowing a currency to "float" is to allow the exchange rate of the currency to change depending on the currency exchange market. People can buy and sell at different prices so the demand for the currency will determine the rate at which it is exchanged.

This is in contrast to a "fixed" currency which has a value tied to that of another currency or even something like gold.
