Enter:
"WASHINGTON (Reuters) U.S. stock index futures indicated a marginal recovery on Wall Street on Thursday, as futures for the S&P 500 rose by 0.34 percent, Dow Jones futures gained 0.12 percent, and Nasdaq 100 futures increased by 0.51 percent at 0921 GMT."
Results should consist of an array containing all numbers, including decimals.
There is a somewhat related discussion on Stack Overflow, but it only focuses on extracting a single number.
Here is a solution that should work:
var message = "WASHINGTON (AP) The Senate passed a new bill with a vote of 53-47, marking a significant victory for the current administration. The bill is expected to have a positive impact on the economy.";
console.log(message.match(/(\d[\d\.]*)/g));
To eliminate any invalid numbers like 99.99.99, you can use the following code:
var validNumbers = [];
message.replace(/(\d[\d\.]*)/g, function( number ) { var num = Number(number); if (number == num) { validNumbers.push(number); } })
Here is an example of a regular expression that should do the trick:
/[-+]?[0-9]*\.?[0-9]+/g
Let's test it out:
"The weather forecast predicts a high of 75 degrees Fahrenheit and a low of -5 degrees Celsius.".match(/[-+]?[0-9]*\.?[0-9]+/g)
Running this test gives us the following results:
["75", "-5"]
