Numeric literals

Numeric literals entered with E notation are treated as float; all others are treated as exact numerics:

• Literals between 2³¹ - 1 and -2³¹ with no decimal point are treated as integer.

• Literals that include a decimal point, or that fall outside the range for integers, are treated as numeric.

  To preserve backward compatibility, use E notation for numeric literals that should be treated as float.
