Instance Method Details

#get_1float(sign = true) ⇒ String

get only the digits and + - . , symbols in the string from the first group of digits you should see also #get_float and #get_1int

Parameters:

  • sign (true or false or :less) (defaults to: true) —

    if true, keep the - and + signs, if :less, only keep -

Returns:

end

#get_1floats(sep = ' ', sign = true) ⇒ Array of String

get all floats groups if sep is a sign and the param sign == true, then theses signs will be splited first see also #get_float and #get_ints

Parameters:

  • sep (String or Regexp) (defaults to: ' ') —

    separator

  • sign (true or false or :less) (defaults to: true) —

end

#get_1int(sign = true, sep = '') ⇒ String

It take every digits (and sign - see param sign) of the first group of digits and return them. For exemple, “+3 4”.get_1int will return “+3” you should see also #get_int #get_ints and #get_1float
