[2.37] Bug(?) with if statement involving strings and numbers
|
If you attempt to compare a string against a number you will always get a true statement, as in #if (H > 60) {#show true} {#show false}. This came up with me using a script that would capture a variable which was sometimes a number and sometimes a string, so i used a command like
#if ((@testvar > 50) or (@testvar = H)) {do this} {do that}, so whenever it was a string it would automatically evaluate to true unless i do an %int(@testvar) which solves it, I don't know if its just programming practice, but I would think that a string being compared to a number would always default to false |

Heh. Not necessarily so. I thought it was ascii values at first, but apparently not. Hmmm...

It doesn't matter which it returns, really, because either one isn't really right. If you care about the variable sometimes containing a string, check if it contains a number before you start working with it.
