I am trying to build a conversion calculator fractions to decimals.

I have this an it works except it always puts in a leading zero. if I want to add a number before the anwer like 2 3/4 the result will be 20.75.

CODE

<?php
/// Get Numbers and Set Variables ///
$numerator1 = $_POST['numerator1'];
$denominator1 = $_POST['denominator1'];
$numerator2 = $_POST['numerator2'];
$denominator2 = $_POST['denominator2'];
$number3 = $_POST['number3'];
$number4 = $_POST['number4'];

/// Math ///
$mult1 = $numerator1 / $denominator1;
$mult2 = $numerator2 / $denominator2;

/// Convert to 3 places after decimal ///
$final1 = number_format($mult1,3);
$final2 = number_format($mult2,3);

/// Print Final Numbers ///
print "$number3$final1";
print "$number4$final2";
?>

Is there away to remove the 0 from the 0.75 so it will output 2.75?

Thanks,
Josh

Nevermind

All I had to do was add.

CODE

<?php
/// Get Numbers and Set Variables ///
$numerator1 = $_POST['numerator1'];
$denominator1 = $_POST['denominator1'];
$numerator2 = $_POST['numerator2'];
$denominator2 = $_POST['denominator2'];
$number3 = $_POST['number3'];
$number4 = $_POST['number4'];

/// Math ///
$mult1 = $numerator1 / $denominator1;
$mult2 = $numerator2 / $denominator2;

/// Add Full Number ///
$result1 = $number3 + $mult1;
$result2 = $number4 + $mult2;

/// Convert to 3 places after decimal ///
$final1 = number_format($result1,3);
$final2 = number_format($result2,3);

//Print Final Numbers
print "$final1";
print "$final2";
?>
