[Gnuplot-bugs] Gnuplot miscalculates formula badly

[ariadland <ari...@gm...>]

I plotted the following function in gnuplot (version 4.2   patch 5)

plot [.5:1.5] 1/(1/2.9898+94*(-x**2+1)**2*(-x**2+4/3)**2)  

The resulting figure should have two peaks.  One at x=1,  and one at about
x=1.2.  Gnuplot, however, just shows one smooth peak.

When I type in

plot [.5:1.5] 1/(1/2.9898+94*(-1.2**2+1)**2*(-1.2**2+4/3)**2)  

gnuplot returns a value that is horribly wrong  (checked by mathematica and
matlab).

Does it have something to do with the division?  I'm not sure,  but this is
a serious flaw.
