The 64 bit version of VisualWorks Smalltalk has an immediate ShortDouble, which sacrifices two bits of exponent for a tag. It thus has the same precision as an IEEE double, but one fourth as much range. Overflows automatically get promoted to ordinary Double's, which are pointers to objects holding real IEEE doubles.
