How are variables scoped in C – Static or Dynamic? A double is 2x the size of a float. The float value is a 32-bit number with floating point , the variable double is 64-bit or 80-bit long and therefore more precise. Based on the precision level, we are going to discuss the differences between the two. The main difference is Floats and Doubles are binary floating point types and a Decimal will store the value as a floating decimal point type.
