I know that VS 2010 has F# 2.0 and VS 2012 - F# 3.0.
But how I can get F# version number, for example in F# interactive? Is there some command, for example:
#ver;;?
Thanks.

The F value is a value on the F distribution. Various statistical tests generate an F value. The value can be used to determine whether the test is statistically significant. The F value is used in analysis of variance (ANOVA). It is calculated by dividing two mean squares.
The F column, not surprisingly, contains the F-statistic. Because we want to compare the "average" variability between the groups to the "average" variability within the groups, we take the ratio of the Between Mean Sum of Squares to the Error Mean Sum of Squares. That is, the F-statistic is calculated as F = MSB/MSE.
When you start up F# Interactive window in VS, you get something like:
Microsoft (R) F# 2.0 Interactive build 2.0.5.0

For help type #help;;
> [Loading init.fsx]

which includes everything you need.
To open F# interactive window one can press : Ctrl+Alt+F.
Update (5/16/2018):
Information format seems to have changed a bit in VS 2017. Language version comes in the end :
Microsoft (R) F# Interactive version 10.1.0 for F# 4.1

It's written in Windows' control panel's programs and features.
