[Gnuplot-info] nan

[Patrick D. <pd...@gm...>]

Hello,

Setting
fcn(x,g,G)=-imag(1/(x+I*g)*faddeeva(x/G)

plot [-30:30] fcn(x,0.01,1)  

provides
nan from values less than -27.28 and more than 27.28
There is not reason for that
The value are small, but not very small
slightly less than
-0.0007586274478

Any idea?

Thank
