Your first task in the script block is to declare some variables. The variable
myString
is declared and
initialized to the string you want to convert. You could just as easily have used the string directly in this
example rather than storing it in a variable, but in practice you'll find that you use variables more often
than literal values. You also declare the variables
myInt
and
myFloat
, which will hold the converted
numbers:
var myString
=
"56.02 degrees centigrade";
var myInt;
var myFloat;
