I have a very specific question for JavaScript:

I have the following string: 

var prueba ="Hola mundo 5.26"

I need to extract the decimal number from that string. How can this be done?

Thank you very much

Try this regular expression 

var resultado = prueba.match(/[0-9]*\.[0-9]*/g)

You can get the number within a string like this: 

var prueba = "Hola mundo 5.26";
var numero = parseFloat(prueba.match(/\d+(\.\d+)?/g));

Good luck!
