写了一个求最大值与最小值的函数

function max(info)
arr=split(info,",")
max=clng(arr(0))
for i=1 to ubound(arr)
if clng(arr(i))>clng(max) then
max=clng(arr(i))
end if
next
end function

function min(info)
arr=split(info,",")
min=clng(arr(0))
for i=1 to ubound(arr)
if clng(arr(i)) min=clng(arr(i))
end if
next
end function
‘’调用方式
‘’i=max("12,23,12,12,,32,43,54,43,56")
‘’i=min("12,12,23,3,454,34,4,5,45,3,232,3,2,43,4")
