例如:2.44444。 我需要先到点数——就我而言是<条码>4。 如何执行?
How about
( (int)(floor( fabs( num ) * 10 ) ) ) % 10
页: 1 把它交给你们,希望它能够帮助
#include<stdio.h>
int main()
{
int b;
float a;
a=2.4444; load some value
b=(int)a; typecast it into integer you get 2 into b variable
a=a-b; subtract b from a and you will get decimal point value 0.4444
a=a*10; multiplying with 10 gives 4.444
b=(int)a; now apply the same logic again
printf("%d",b); outputs 4
}

it could be as simple as
num*10%10
(int)(num * 10) - ((int)num) * 10
