You might want to look at Ada for existing practice.

In C, a constant with either a decimal point or an exponent is
floating-point.  In Ada, 1.0e6 is floating-point and 1e6 is an integer.
Of course this isn't very helpful if you want to represent numbers with
a lot of non-zero digits; for that, you need digit separators.
