I was kind of surprised that PHP did not have a built-in floating point random number function. So I created my own:

<?
// Floating point random number function
// April 2007, René W. Feuerlein
function fprand($intMin,$intMax,$intDecimals) {
  if($intDecimals) {
    $intPowerTen=pow(10,$intDecimals);
    return rand($intMin,$intMax*$intPowerTen)/$intPowerTen;
  }
  else
    return rand($intMin,$intMax);
}

// Example of fprand function
for($i=0; $i<=5; $i++) {
  echo "Three random numbers with $i decimals are: ";
  for($ii=1; $ii<=3; $ii++)
    echo fprand(1,10,$i).' ';
  echo '<br>';
}
?>
