Not really ariel, it has more to do with how many bytes thr number will occupy in memory. A single precision floating point number takes 4 bytes of space in memory. This is enough for normal operations where decimals are needed. But, for operations where a lot more precision is needed, like scientific calculations, 4 bytes is not enough. The double precision floating point number takes 8 bytes of space. This allows us to store longer and more precise numbers. That's basically it.

double precision Floating Point Numbers have a decimal point, known as floating point. How many digits could be used, before and after the floating point, depends on op- system and memory !

Double precison floating numbers are numbers that may have a dot "." in them and exactly two digits after the dot. for example 10.72, 2.01, 82.31, 8.00
