Can somebodyt shed some light on this behavior?
code:

? ''+55+'.'+123
? 55+'.'+123


The first line results in: 55.123
The second line results in: 178

Apparently, the second line ingnores the '.' and just adds the numbers before displaying them.

Just weird.

Hey Jens,

Ruud gave a dissertation on this somewhere, sometime ago. I'll see if I can find a link to it.

In the meantime, the short answer is that an expression evaluates to the "type" of the first operand. So if an expression starts with a string, it will evaluate to a string. If it starts with a number, it will evaluate to a number ... this explains the behavior of :


? "kix" + 32 + "kix"


displays: kix32kix


? 32 + "kix" + 32


displays: 64
