lejp: E implies float

Browse source 
Since eg, 1e-3 is a float without needing a decimal point, let's just
    generally take it that anything with the exponent token is a float, ie, 1e3
    is also a float despite it can be expressed as an integer.

    This seems right also because E is itself not valid in an integer.
