is datastage accept negative numbers

[pavankatra]

Hi,
I have stagvariable like
If (IsValid("int32", Sv9Digits) And(IsValid("string", Sv10thChar))) Then ((9*0)- (DSLink3.ISBN [1,1])) Else 'N'.


First charecter is 1 then it will return -1.My doubt is whether datastage accept the negative numbers or not.

Can anyone please help me on this.

Thanks In Advance.

Thanks

int32 is a signed 32-bit integer.

If you don't want signed numbers, uint32 is an unsigned 32-bit integer.

Not sure what you're trying to accomplish. (9 * 0) will always be 0. IsValid() always returns true for "string" (unless the value is null).

Yes, of course it will accept negative numbers. I must admit, however, your derivation confuses me... you multiple 9 by 0? To what end, just to get a zero? And then set a variable to either an 'N' or a negative number? Kind of an odd way to flip the sign, if you ask me.

Other than that, why the doubt? What issue are you having with this?
