differences between strings and numbers

[611brain]

I have script sample but i don't understand
here is my script:

<%
dtrfirstnum = “35”
intsecondnum = 40
strthirdnum = “50”
inttotal = strfirstnum * intsecondnum
Response.write inttotal
%>

what is different between "35" and 35.. for example:

intsecondnum is "40" and strthirdnum="56"
response.write intsecondnum * strthirdnum

and

intsecondnum is 40 and strthirdnum="56"

response.write intsecondnum * strthirdnum
OR

response.write intsecondnum + strthirdnum

can you please explain me what is differences between "" and without "". how does this caculation works? what is different between them?

thanks

All variables in VBScript are Variant.
Using math operator (like *) coerce the operands to numeric.

Hope This Helps, PH.

To be safe, always convert to the correct type and never use + for string concatenation: always use &

one = "12"
two = 23
intval = cint(one) + two ' will give 35
strval = one & cstr(two) ' will give 1223
