Re: [Gnuplot-info] int() strange behaviour

[Simon G. <tar...@gm...>]

Ok, thank you for being kind with my ignorance.
Anyway in my particular situation these "missed approximations"
have a disastrous effect, since I'm creating classes for an hystogram:

gnuplot> print int(19.1/0.1)
191
gnuplot> print int(19.2/0.1)
191
gnuplot> print int(19.3/0.1)
193
gnuplot> print int(19.4/0.1)
193
gnuplot> print int(19.5/0.1)
195
gnuplot> print int(19.6/0.1)
196
gnuplot> print int(19.7/0.1)
196
gnuplot> print int(19.8/0.1)
198

Undoubtedly unconvincing classes.
I'm bypassing it using

bind(x, l) = int(x/l) * l
plot 'data' using ( bind($1 * 10**6, width * 10**6) * 10**(-6) ): [...]

I think that for my particular data (19.1, 19.5, 19,6, 19.2, ... ) can be
used also

plot 'data' using ( bind($1 +0.05, width) ): [...]

or even the suggested "+ eps".
Well, this was my really problem!
Thank you again for explanations
