public class Arith
extends java.lang.Object
Class to speed up some SMSQ/E floating point ari ops.
Some notes:
On the d1/d2 operations, d1 = mantissa, d2 - exponent.
tos=top of stack, pointed to by (a1)
nos=next on stack, pointed to by 6(a1)
SMSQ/E FPs have a 12 bits exponent, and a 31 bits mantissa + sign bit(bit 31 of the long word is the sign bit).
IEEE doubles (64 bits) "only" have an 11 bits exponent, rest is mantissa + sign bit (bit 63), so there might be some s
SMSQ/E can handle that IEEE can't : they are handed back to SMSQ/E.
