title: Compression algorithms for numbers only
body: <p>I am to compress location data (latitude,longitude, date,time). All the numbers are in fixed format. 2 of them (latitude,longitude) are with decimal format. Other 2 are integers.</p>
  
  <p>Now these numbers are in fixed format string. </p>
  
  <p>What are the algorithms for compressing numbers in fixed format? 
  Is number only compressions (if there any) better than string compression? 
  Should I directly compress string without converting it to numbers and then compress?</p>
  
  <p>Thanks in advance.</p>
