Proof step 4 from proof le-add (
previous step
)
⊦ ¬ mkDecimal(i0 - i, j) < dec ↔ dec ≤ mkDecimal(i0 - i, j)
User applied rule insert rewrite lemma
And obtained the following new goals
Proof step 5
:
⊦ dec_i ≤ dec_j ↔ ¬ dec_j < dec_i
Rule argument
spec: inst: name: le-def seq: ⊦ dec_i ≤ dec_j ↔ ¬ dec_j < dec_i subst: [dec_j, dec_i] → [mkDecimal(i0 - i, j), dec] flags: rewrite, current
Additional information
Used terms: mkDecimal(i0 - i, j), dec
