Parsing bug?

[Daniel <boy...@gm...>]

Hi folks,

I just tried plotting this equation,

T0 = 300
T1 = 6000
set xrange [T0:T1]
f(x) = (1 - x**4/T1**4) * (1 - T0/x)

Which should have two zeros at (x=300 and x=6000). It seems that because the numbers have been defined as integers it give the wrong result. Redefining,

T0 = 300.
T1 = 6000.

plots the correct function.

Is there a case for converting ints to floats as standard in the gnuplot interpreter? When using gnuplot as a user, I would expect the maths to just work without having to think about programming details like ints of floats. In a programming environment of course this is what I would expected.

Cheers,

Dan
