title: JavaScript: represent float as product of integer and power of ten
body: <p>For instance, I have float 1.1111111111 and need to get 11111111111 and 10.</p>
  
  <p>I want to avoid functions, which may change part after point as I need it to show metric prefixes.</p>
  
  <p>It may look simple with strings, I am just not sure if it is a proper way in JavaScript.</p>
