Question

不确定为什么，但是awk将我的变量 x 舍入为2dp或正则表达式模式以测试整数是否不能正常工作。

我的代码：

awk 'BEGIN{for (i=972286200; i<=972384300; i=i+900) {x=((i/86400)-0.375); if(x ~ /^[0-9]+$/ ) {s=i} printf("%010d,%.3f,%010d\n",i,x,s)}}'

代码正在尝试创建具有如下列的数据集：

i-数据增加900
x-测试数据是否被数字除
s-如果除法是整数，则使用 i ，如果不使用先前的整数 i

当前产生：

Answer 1

改为使用x==int(x)进行int测试。

$ awk 'BEGIN {for(i=972286200; i<=972384300; i+=900) 
                {x=(i/86400)-0.375; 
                 if(x==int(x)) s=i; 
                 printf "%010d,%.3f,%010d\n",i,x,s}}'

还改变了一些小事。
