How I can simplify it:
params[:value] =~ /^\d+$|^-\d+$|^\d+\.\d+$|^-\d+\.\d+$/

The easiest check is to use Float and Integer:

Float("foo") rescue false

=> false

Float("1") rescue false

=> 1.0

Integer("10") rescue false

=> 10

Integer("10.4") rescue false

=> false

Kind regards

/^ [-+]? \d+ (\. \d+)? $/x
