-# In most langauge, unlimited size integers are done using string math

-
-# Bigint's are really just strings.
-
-# Mathematics routines for bigint's:
-
-# bneg(BINT) return BINT negation
-# babs(BINT) return BINT absolute value
-# bcmp(BINT,BINT) return CODE compare numbers (undef,<0,=0,>0)
-# badd(BINT,BINT) return BINT addition
-# bsub(BINT,BINT) return BINT subtraction
-# bmul(BINT,BINT) return BINT multiplication
-# bdiv(BINT,BINT) return (BINT,BINT) division (quo,rem) just quo if scalar
-# bmod(BINT,BINT) return BINT modulus
-# bgcd(BINT,BINT) return BINT greatest common divisor
-# bnorm(BINT) return BINT normalization
