How to convert string to float?

[Jason Chan]

i want to covert a querystring to float number in asp.
what function should i use?

i know cint() can convert string to int
but how about float?

hi,

usually you can use the round function.
As asp deals with the variant type, something tlike that should work

'querystring : ?id=1&value=10.874
id=request.querystring("id")
v=request.querystring("value")
v=round(v,3)

CDbl() or CSng() will do the trick. Use IsNumeric() to make sure it's
numeric first.
