A floating-point number (float) consists of a sequence of digits with an embedded decimal point, optionally preceded by a minus sign (-), and optionally followed by an exponent consisting of upper- or lowercase ‘E’ and a signed base 10 integer. Examples of floats are:

     1.0   -23.45   187.6E12   -0.0234e15   12.0E-2

Note that there must be at least one digit before, and one digit after, the decimal point.
