Please consider this
| 3.25 | 0.4875 |
| | 0. |
| 2.25 | 0.3375 |
#+TBLFM: $2=$1*0.15
How can I avoid the entry 0. ?
I could insert **
Giving
| 3.25 | 0.4875 |
| ** | #ERROR |
| 2.25 | 0.3375 |
#+TBLFM: $2=$1*0.15
But this is cumbersome, any other possibilities?
Thanks

One possibility:
| 3.25 | 0.4875 |
| | |
| 2.25 | 0.3375 |
#+TBLFM: $2=if("$1" == "nan", string(""), $1*0.15);E

Great but how can I round?
#+TBLFM: $2=if("$1" == "nan", string(""), $1*0.15;%.1f);E
And friends did not work any more
| 3.25 | 0.5) |
| | 0.0) |
#+TBLFM: $2=if("$1" == "nan", string(""), $1*0.15;%.1f);E

This is invalid syntax, what you meant would be:
| 3.25 | 0.5 |
| | 0.0 |
#+TBLFM: $2=if("$1" == "nan", string(""), $1*0.15);E %.1f
To preserve empty columns when reformatting you can use the Calc
formatter:
| 3.25 | 0.5 |
| | |
#+TBLFM: $2=if("$1" == "nan", string(""), $1*0.15);E f-1
(info "(org) Formula syntax for Calc")
`if("$1" == "nan" || "$2" == "nan", string(""), $1 + $2); E f-1'
Sum of the first two columns. When at least one of the input
fields is empty the Org table result field is set to empty. `E'
is required to not convert empty fields to 0. `f-1' is an
optional Calc format string similar to `%.1f' but leaves empty
results empty.
