(a) A floatdcl can be represented as either f or float, allowing a more Java-like syntax for declarations.
(b) A intdcl can be represented as eitheri or int.
(c) A num may be entered in exponential (scientific) form. That is, an ac num may be suffixed with an optionally signed exponent (1.0e10, 123e-22 or 0.31415926535e1).
