Answer 1

You can try this regex

^\d+\.\d{6,15}$

REGEX DEMO

Explanation:

\d{6,15} match a digit [0-9]
Quantifier: {6,15} Between 6 and 15 times, as many times as possible, giving back as needed [greedy]

Answer 2

The regular expression:

/^\\d+\\.\\d{6,15}$/

Should do it.

• ^ - From beginning of input
• \\d+ - One or more digits [0-9]
• \\. - Decimal place
• \\d{6,15} - Between 6 and 15 digits [0-9]
• $ - To end of input

To test:

var regexp = /^\d+\.\d{6,15}$/;

var test = function (input, result) {
  if (regexp.test(input) === result) {
    console.log('OK');
  } else {
    console.error(input, result);
  }
}

test('0.0001', false);
test('12310.002301', true);
test('531412.135143613411552', true);
test('531412.1351436134115515', false);
