C语言 将一个字符串中的浮点数全部变为整数

在压缩精简svg文件的路径时非常有用

//fumiama 20200802
//allFloat2Int.c
#include <stdio.h>
#include <string.h>
#include <ctype.h>

#define INPUT argv[1]

int main(int argc, char **argv){
    
    
    int len = strlen(INPUT);
    int i = 0;
    while(i < len){
    
    
        if(isdigit(INPUT[i])) {
    
    
            float x = 0;
            sscanf(&INPUT[i], "%f", &x);
            printf("%d", (int)round(x));
            while((isdigit(INPUT[i]) || INPUT[i] == '.' ) && i < len) i++;
        }else putchar(INPUT[i++]);
    }
    putchar('\n');
}

编译好之后直接使用：
