You may use

^([0-5](?:\.\d)?|6(?:\.0)?)$

See the regex demo

Details:

  • ^ - start of string
  • ( - start of an alternation group:
    • [0-5](?:\.\d)? - a digit from 0 to 5 followed with an optional sequence of a . followed with a single digit
    • | - or
    • 6(?:\.0)? - 6.0 or 6
  • ) - group end
  • $ - end of string
