Yes:

--> gca().ticks_format(1) = "%.1f";

Because of the bug 14790 <http://bugzilla.scilab.org/14790>, new ticks 
labels are not rendered. But there is a work-around:

--> a = gca(); a.x_ticks.labels(1) = a.x_ticks.labels(1);

forces displaying new ticks labels.
As an expected side effect, this automatically sets a.auto_ticks(1) = 
"off", but labels are well formatted.
Example:

x  =  0:0.1:2;
plot(x,sin(5*x))
a  =  gca();  a.ticks_format(1)  =  "%.1f";
a.x_ticks.labels(1)  =  a.x_ticks.labels(1); HTH Samuel
