actually, I don't know if you want all the numbers out, you can try like this:

var str = "6Pay-30D 3Pay-30D 19.95-1st Pay Amount 3Pay-30D SH3Pay";
str.match(/\d+(\.\d+)?/g);

below is the output:

['6','30','3','30','19.95','1','3','30','3']

if you just want "19.95" in the input. you'll try like this:

str.match(/\d+(\.\d+){1}/g);

below is the output:

[ '19.95' ]

finally, if you just want first matched result, just remove the 'g'. hope it helpful.
