Ok,

_v_ is the result of a formula and height = 1

if i go

```auto

trace (height + *v*) 

```

i get

**1** 6378143.50006376

seems like its just concatenated a string

if i use

```auto

trace (*v* + height) 

```

i get

6378143.500063761

which is correct…

can someone please explain this oddness to me, it has me perplexed, because to me both the trace statements are identical really…

Ray.
