get number value of an output to another script java

Two different scripts cannot use the same variable unless one script invoke the other script.
To use value of var a in script 1 (which has an output in html), use function parseFloat.
<script>
	a = 1.5 + 2
  	$("#a").text(a)
</script>
<script>
	b = parseFloat(a) + 2
  	$("#b").text(b)
</script>
