我不能找到任何官方的东西,它说这个。 C
标准是否要求最低位数?
I can''t locate anywhere official-looking that it says this. Does the C
standard mandate some minimum number of bits?

显然,最小值是10位十进制数。随着指数的增加,32位
是不够的。
实际上,双倍可能是64位。但是对于C,一切都没有。
肯定。

Aparently the minimum is 10 decimal digits. With the exponent added, 32 bits
is not enough.
In practice a double will likely be 64 bits. But with C nothing is ever
certain.
