JS Regular expressions determine numbers and range of numbers (summary)

To determine the regular expression of a number:

/^\d+$///nonnegative integer (positive integer + 0)/^[0-9]*[1-9][0-9]*$///Positive integer /^ ((-\d+) | (0+))                                                                    $///non-positive integer (negative integer + 0)/^-[0-9]*[1-9][0-9]*$///Negative integer                                                                     /^-?\d+$///Integer /^\d+ (\.\d+)? $///nonnegative floating point number (positive floating point + 0)/^ (([0-9]+\.[ 0-9]*[1-9][0-9]*) | ([0-9]*[1-9][0-9]*\. [0-9]+) | ([0-9]*[1-9][0-9]*)) $///Positive floating point/^ (-\d+ (\.\d+)?) | (0+ (\.0+)?)) $///non-positive floating-point number (negative floating-point number + 0)/^ (-([0-9]+\.[ 0-9]*[1-9][0-9]*) | ([0-9]*[1-9][0-9]*\. [0-9]+) | ([0-9]*[1-9][0-9]*))) $///Negative floating point/^ (-?\d+) (\.\d+)? $///floating-point number
