Floating-point is represented as the integral part of the number,
followed by a decimal point and the fractional part of the number.

var x=.333333333333333333;
var y=6789.3476;

You can also express the floating-point values with exponential notation.
This is done by putting the character e (or E) after the decimal digits,
followed by an optional plus or a minus sign, followed by an integer exponent.
