How do I format the result of 0.5 to show as 50p ?

depends where??
if the 0.5 is contained in a variable, you simply insert the variable into a text box, and put a 'p' after it :-)

<variable>p
you can also concatenate the variable with "p"
var1=var1+"p"

Thank you for your reply. I'm now sorted.

What I wanted:

0.1 to become 0.10
or
1 to become 1.00
or
1.1 to become 1.10

I found this script that may help others:

you will need two variables: ans and num

- num is your start number (eg 0.1)
- ans will be the answer (eg 0.10)

on a button I placed the following code:

Code:

round_decimals(num,2)

Then in the main code of the page I used:

Code:

function round_decimals(original_number,decimals){
    var result1 = original_number * Math.pow(10, decimals)
    var result2 = Math.round(result1)
    var result3 = result2 / Math.pow(10, decimals)
    return pad_with_zeros(result3, decimals)}   /* calls pad_with_zeros function */

function pad_with_zeros(rounded_value, decimal_places){
    var value_string = rounded_value.toString()
    var decimal_location = value_string.indexOf(".")
    if (decimal_location == -1){
      decimal_part_length = 0
      value_string += decimal_places > 0 ? "." : ""}
    else {
        decimal_part_length = value_string.length - decimal_location - 1}
    var pad_total = decimal_places - decimal_part_length
    if (pad_total > 0){
    for (var counter = 1; counter <= pad_total; counter++) 
    value_string += "0"}
    return ans=value_string}

On my page I have a text box with:' £<ans> 'to show my result.

sorry--I misunderstood what you were asking, but now I see. An interesting solution.
