这里是一些例子。
数字值 | 指数表示法 |
---|---|
1,000,000,000 | 1.0e9 |
123,000 | 1.23e5 |
322.56 | 3.2256e2 |
0.000056 | 5.6e-5 |
以下代码以两种方式显示浮点值。
#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;
}
