Serial print question

Using Arduino Programming Questions

Does any one know what the "f" means in this piece of code, I have tried to find out with no luck.

Serial.println(loc.lat/10000000.0f,8);

Thank you for your help.

It is informing the compiler that the number is of the floating point variety. No really necessary since using a decimal in the number makes it a floating point number.
