I just had a horrible idea. Decimal is commonly used with fixed point (no speed penalty), whereas binary is commonly used with floating point. But what if... what if they had a bastard child? What if we moved the point a fixed distance in decimal... and also a floating distance in binary? The value represented would then be sign * mantissa * 2^exponent * 10^bias With a bias of -6, you could represent every multiple of 0.000001 up to 9 billion if I did the math correctly.
