Hi,
how can i determine the maximum size of `double' without printing out
DOUBLE_MAX ?
And what about the precision of a `double' , anyone give a try ?

Kinda of significance digit. For example:
B A number `12.340' , and if say it has 2 digits' precision , then we
consider the `0' is not accurate , while `.34' is accurate.
What?!
Assuming 64-bit double, it has a mantissa of 52 bits and an exponent of
11 bits. If the mantissa is all-ones, that will give a significant of
2-2^(-52). The exponent cannot be all-ones (an all-ones exponent means
infinity or NaN), so the largest exponent is 2^11-2 = 2046, minus bias
