Both were already in 4.1. Round() is undocumented, and it rounds the 
number entered to the nearest integer. In the console, try:

print round(10.8)
forward 20
print round(10.3)
forward 20

And you will see that it will print
11
10

The math functions are listed in the "Can the Turtle do math?" page of 
the doc, but there are no explanation of what each one does. Niels 
mentioned he thinks it would be nice to have a small explanation for 
each. Currently the text is:

"KTurtle has advanced mathematical features. It knows the number pi and 
trigonometrical functions like sin, cos, tan, arcsin, arccos, arctan and 
the functions sqrt and exp."

On the other hand, people that want to use these functions probably know 
what they are supposed to do, so if we are writing the docs for kids 
maybe a full description is not needed.

You asked previously about the console: it is the lineedit widget 
available in the toolbar that you can use to enter a one line command 
and test it. It is available in 4.1 and trunk as well, but undocumented.
