## Re: [Help-smalltalk] Float printString?

```Dear Holger,

The inspect is here, whatever it means..

An instance of FloatD
[1]: 224
[2]: 221
[3]: 240
[4]: 122
[5]: 184
[6]: 184
[7]: 41
[8]: 191

Instead of an inspect I checked the values in the calculation:

quo := (endHeight-startHeight)/length.
quo inspect.
Transcript showCr: 'endHeight: ',endHeight printStringIfNecessary.
Transcript showCr: 'startHeight: ',startHeight printStringIfNecessary.
Transcript showCr: 'length: ',length printStringIfNecessary.
Transcript showCr: 'Lejtés: ',quo printStringIfNecessary.       #<-----
error happens here

Printout:

endHeight: 99
startHeight: 110.0
length: 56053.86243369161
*<same error msg here>*

Calculating the same in bc

(99-110.0)/56053.86243369161
-.00019623982224262149

Best regards
Robert
