Show a number to two decimal places
(25 answers)
Closed 5 years ago.
I'm currently working on retrieving data from coinmarketcap API and I would like to limit the strings to 5. I retrieve the data and then multiply the value *1.07 and the result to MXN, but the string is long, like 25.65675734343, I want to limit that string, this is my echo:
echo $xrpprice*$rate*$fxrates['rates']['MXN'];
Use round:
$result = $xrpprice*$rate*$fxrates['rates']['MXN'];
echo round($result,2);
In PHP you can use number_format to control how many decimal places. Assuming you don't want to limit the whole number to just five characters.
echo number_format($numberToFormat, $numberOfDecimalPlaces);
Please better explain your question. Also, what have you tried?

I am trying to add the int with strings in PHP but I could get a helpful answer on StackOverflow and other website communities.
I want the code separate the ALPHABETS and NUMBER and then add the value in NUMBER and again JOIN the ALPHABETS AND ADDED NUMBER together.
How I achieve this, Please help.
Example:
$mynumber = 'SBI0001';
$addValue = '1';
It will be 'SBI0002' in PHP.

Hello there i have problem in jQuery. Suppose i have a value like 20000. And i want the value like 20,000 that after two number a comma will be inserted. I can't do it using jQuery. Please anyone help me out.
Since you said you want the comman inserted "after two numbers", I'm going to assume you have the easy case where you know that your input is a 5 digit number and don't want a more generic number formatting solution. In that case you can do something just like:
var num = 20000;
num = num.toString();
num = num.substr(0,2) + ',' + num.substr(2);
// Now num === "20,000"
Note that 20,000 will only read as twenty-thousand in certain locales. It could be read as just twenty in many locales, but 20000 will be read correctly by anyone who understands Arabic numerals.

Character-wise string diff in PHP

Is it possible to return the number of characters which differ between two strings?
In my case, I would like to run a check to quantify how much a user's draft has changed vs the database version. With this information, the system can decide weather or not the draft needs to be auto-saved.
For example:
echo string_diff("Hello world", "Hi World");
This should output "5", indicating that characters "ello" & "W" are different.
Is this possible with PHP? How about with mySQL?
On the PHP side your options are
similar_text which calculates the percent similarity between two strings
levenshtein - which calculates the edit distance between two strings (the number of key strokes it takes to transform string a into string b)
on mysql you can use this user defined function to calculate the levenshtein distance

PEAR's Numbers Words is old, but competent.
The duplicate question seems to answer this quite well, DAFFODIL, have a look there. You will have to have PEAR installed. Easiest way is to try Numbers_Words::toWords(200) and see if that throws up an error.
