Convert String With Dot or Comma to Float Number

How can I convert a string with dot and comma into a float in Python

Just remove the , with replace():

float("123,456.908".replace(',',''))

Do a replace first:

parseFloat(str.replace(',','.').replace(' ',''))

How to convert floating point decimal separator from dot to comma in Javascript

parseFloat("2,83") will return 2 because , is not recognized as decimal separator, while . is.

If you want to round the number to 2 decimal places just use parseFloat(discval.toFixed(2)) or Math.round(discval * 100) / 100;

If you need this jut for display purposes, then leave it as a string with a comma. You can also use Number.toLocaleString() to format numbers for display purposes. But you won't be able to use it in further calculations.

BTW .toFixed() returns a string, so no need to use .toString() after that.

Converting a number with comma as decimal point to float

Using str_replace() to remove the dots is not overkill.

$string_number = '1.512.523,55';
// NOTE: You don't really have to use floatval() here, it's just to prove that it's a legitimate float value.
$number = floatval(str_replace(',', '.', str_replace('.', '', $string_number)));

// At this point, $number is a "natural" float.
print $number;

This is almost certainly the least CPU-intensive way you can do this, and odds are that even if you use some fancy function to do it, that this is what it does under the hood.
