logarithmic plot does not format tick values with decimal point

[alaingdl]

(tested with the current Git version)

a=ABS(randomn(101, 1000))
plot_io, a, yr=[0.1, 10],/yst     ; (same as plot,/ylog, a, yr=[0.1, 10],/yst)

In IDL, the legend for yrange go from 0.1 to 10.0, What is displayed : 0.1, 1.0, 10.0

In GDL, it seems that digits are missing : 0, 1, 10 are displayed

a bug indeed!

a=ABS(randomn(101, 1000)) & plot_io, a, yr=[0.1, 10] plots correctly. This is weird.

In fact, I did not realize that without /ystyle it was OK, because we are trying to make a large set of figures with a given fixed range. 😄

this is a classic: IDL uses floats, we use doubles. This should do the trick. Needs to be well tested, though, as it may have consequences elsewhere...
