一个简单但是实用的小函数,asp的

大家在做某种数据显示的时候是不是经常遇到这样的情况，太大的数字显示成科学计数法，而比小数则显示成.555这样，非常不美观，可以用以下小函数搞它
function sonic(tnum)
if csng(tnum)>0 then
        getlar=0

      if instr(tnum,"E")>1 then
            tnum=tnum/10000
            getlar=1
      else
    if instr(tnum,".")<1 then
        tnum=cstr(tnum)&"."
        end if
    if instr(tnum,".")=1 then
        tnum="0"+cstr(tnum)
        end if
      end if
        if getlar=0 then
       sonic=left(tnum&"00",instr(tnum,".")+2)
        else
           sonic=left(tnum&"00",instr(tnum,".")+2)+"万"
        end if
elseif csng(tnum)<0 then
    tnum=-csng(tnum)
    if instr(tnum,".")<1 then
        tnum=cstr(tnum)&"."
    end if
    if instr(tnum,".")=1 then
        tnum="0"+cstr(tnum)
    end if
    sonic="-"&left(tnum&"00",instr(tnum,".")+2)
else
    sonic="0.00"
end if
end function

很简单的哦
