Sizeof
One is single precision, is a double
Floating point arithmetic consume time, general numerical calculation, the decimal point too many digits is meaningless,
The design principle of C is efficiency, so where do not need to double with single precision,
But in order to support the mathematical operation, as there are liberian, don't know to achieve the same,
