Proof step 1 from proof getint-abs (conclusion)

⊦ abs(dec).int = abs(dec.int)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ abs(dec_i) = mkDecimal(abs(dec_i.int), dec_i.scale)
Proof step 3:
⊦ mkDecimal(abs(dec.int), dec.scale).int = abs(dec.int)

Rule argument

spec: inst: name: abs-def seq: ⊦ abs(dec_i) = mkDecimal(abs(dec_i.int), dec_i.scale) subst: [dec_i] → [dec] flags: rewrite, current
