ValueGuess|null
guessPattern(string $class, string $property)
Returns a guess about the field's pattern.
When you have a min value, you guess a min length of this min (LOW_CONFIDENCE) , lines below If this value is a float type, this is wrong so you guess null with MEDIUM_CONFIDENCE to override the previous guess. Example: You want a float greater than 5, 4.512313 is not valid but length(4.512314) > length(5)
