# include<stdio.h>
int main(void)
{
float f1;
double f2;
long double f3;
f1 = 1.23456780909;
f2 = 56233.652450965890909;
f3 = 65.256661145;
printf("f1 = %f\nf2 = %lf\nf3 = %lf\n", f1, f2, f3);
return 0;
}
int main(void)
{
float f1;
double f2;
long double f3;
f1 = 1.23456780909;
f2 = 56233.652450965890909;
f3 = 65.256661145;
printf("f1 = %f\nf2 = %lf\nf3 = %lf\n", f1, f2, f3);
return 0;
}
输出结果：
f1 = 1.234568
f2 = 56233.652451
f3 = 0.000000
