Theorem longshiftrzero-def
⊦ i l>>> j = bits2int(sublist(0, # fillsgn(64, int2bits(i)), mklist(false, i→n(band(j, 63))) + fillsgn(64, int2bits(i))))
Type: An axiom
Validity: The proof is valid.
Features:
Comment: this axiom uses 64 as a constant, i.e. it can be used only for long shifts. Use i>>> for integer shifts.
Used by:
