请教sas除了转2，10，16进制，能否转其他进制，例如26进制？谢谢

有现在有个问题，我将一个10进位的数值先转成2进位数再经过一些运算后，最后想再把运算后的二进制值转回10进位，但我却转不回去，请问要如何修改才能成功转换呢 ?(最后想将x2值转为10进位数)

286      y=put(x, binary8.);
287       z=y/10000;
288       x1=round (z);
289       x2=x1-1*1000;
290      x3=input('x2',binary8.);

293       put  x= y= z=  x1= x2= x3=  ;
