I have this string: £0,00

Which i want to replace with float 3.95 for instance. But i want to keep the £ and the ","

So result -> £3,95

How would i do it?

--

Added some details:

Will the currency symbol always be a £?  

The currency symbol might be before and sometimes behind the numbers. ie 0,00 kr

Will the separator always be ,, or might it be . or even an arbitrary character?  

The separator might be . sometimes.

Will there always be two decimal places?  

The decimal will always be 2 places.

How many integer digits might there be, and will there be a thousands separator?  

It will not be above 100.

```
function convert (proto, value) {
  return proto.replace (/0(.)00/, function (m, dp) {
    return value.toFixed (2).replace ('.', dp);
  });
}

```

the proto parameter specifies the format, it must have a sub-string consisting of a single 0 digit followed by any character followed by two 0 digits, this entire sub-string is replaced by the numeric value parameter replacing the decimal point with the character between the 0 digits in the proto.
```
<script type="text/javascript">
function Convert(Value) {
    return '£' + Value.toString().replace('.', ',');
}
alert(Convert(3.95));
</script>
