Single precision is faster on some processors and takes half as much space as double precision, but will become imprecise when the values are either very large or very small. double needs 64-bit storage compare to 32-bit storage of float data type. The difference between float and double is that float is a data type, which is a single precision 32 bit IEEE 754 floating point while double is a data type, which is a double precision 64 bit IEEE 754 floating point. ...
