Proof step 1 from proof test-inc-01 (conclusion)

⊦ inc(mkDecimal(99, 2)) = mkDecimal(1, 0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ inc(dec) = mkDecimal(dec.int + 1, dec.scale)
Proof step 3:
⊦ mkDecimal(mkDecimal(99, 2).int + 1, mkDecimal(99, 2).scale) = mkDecimal(1, 0)

Rule argument

spec: inst: name: inc-def seq: ⊦ inc(dec) = mkDecimal(dec.int + 1, dec.scale) subst: [dec] → [mkDecimal(99, 2)] flags: rewrite, current

Additional information

Used terms: mkDecimal(99, 2)
