Slava Pestov f27080498d Remove bignum>float VM primitive, and use bignum/f to implement >float on bignums instead, for a slight accuracy gain. Also, bignum/f now has a more efficient post-scaling algorithm to break the circular dependency on bignum>float 2010-11-24 22:41:15 -08:00

Slava Pestov e4f8448eb1 Fix some problems with arithmetic type inference, exposed by recent changes to log2 word
- declared input type for bignum-shift was stricter than the runtime behavior, leading to bad propagation of type info if shift count was a bignum
- types inferred for type functions which used number-valued/integer-valued/real-valued were not always precise, eg bignum bignum bitxor => integer
- add interval-log2, type function for (log2)
- remove math-class-min, it was useless

Slava Pestov a4d9cdfeb3 Refactor all usages of >r/r> in core to use dip, 2dip, 3dip
Non-optimizing compiler now special-cases dip, 2dip, 3dip following a
literal quotation: this allows us to break the dip/slip meta-circle
without explicit calls to >r/r>
