cent and ucent would be integers with values between 
-170141183460469231731687303715884105728 to 
170141183460469231731687303715884105727 and 0 to 
340282366920938463463374607431768211455, respectively. Their 
implementation would not mean that any kind of 128-bit float 
would also be available. For bigger floating-point numbers 
there's at least two packages on dub:

https://code.dlang.org/packages/stdxdecimal
https://code.dlang.org/packages/decimal

These are arbitrary-precision, and probably quite a bit slower 
than any built-in floats.
