Plouffe's Inverter: polynomial for given root

[zak seidov]

Interestingly, 
when we look for 
0.596071637983321523112805414399681828113325, 
Plouffe's Inverter ( http://pi.lacim.uqam.ca/eng/)
replies:
"Roots of polynomials of 4th degree (coeffs: -9..9)
5960716379833215 = 10+15*x+5*x^3" - 
with wrong sign of the first term.
Is it problem of my browser or what?
Zak
