Proof step 13 from proof int2bits-neg-03 (previous step)

int2bits(2 ^ n→i(# int2bits(~ j)) + j) = boolvar ', j < 0 ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 14:
⊦ 0 ≤ i → int2bits(i) = uint2bits(i)
Proof step 15:
¬ 0 ≤ 2 ^ n→i(# int2bits(~ j)) + j, int2bits(2 ^ n→i(# int2bits(~ j)) + j) = boolvar ', j < 0 ⊦
Proof step 42:
0 ≤ 2 ^ n→i(# int2bits(~ j)) + j, uint2bits(2 ^ n→i(# int2bits(~ j)) + j) = boolvar ', j < 0 ⊦

Rule argument

name: int2bits-pos rotate: F subst: [i] → [2 ^ n→i(# int2bits(~ j)) + j]

Additional information

Used terms: 2 ^ n→i(# int2bits(~ j)) + j
