0x1.f40000000000p+14

    #include<stdio.h>

    int main(void)

{

    float aboat = 32000.0;
    double abet = 2.14e9;
    long double dip = 5.32e-5;
    printf("%f can be written %e\n", aboat, aboat);

    printf(“And it 's %a in hexadecimal,powers of 2 notation\n”, aboat);

    printf("%f can be written %e\n", abet, abet);
    printf("%Lf can be written %Le\n", dip, dip);

    return 0;

}

    为什么第二个printf 会变成And it 's 0x1.f400000000000p+14 in hexadecimal,powers of 2 notation

    而书上是And it 's 0x1.f4p+14 in hexadecimal,powers of 2 notation
