Default Float precision

a float variable has a value of -3.4E38 to +3.4E38 with 6 digit precision. What does it mean to have 6 digit precision. Is this just the number of digits the compiler will display before it truncates the value i.e 3.465783??

Also what is the difference between single and double precision?

thanks

The precision determines the maximum number of digits that shall be output on express floating-point values, counting both the digits before and after the decimal point.
