Proof step 10 from proof int2bytes-rec-neg-05 (previous step)

0 < i, j + 2 ^ (i * 8 - 1) < 0, 0 < j + 2 ^ (i * 8), 0 < 2 ^ (i * 8) + j, j < 0 ⊦ j = 0, bits2bytes(int2bits(j)) = i2b(~1) ' + fix(i→n(i) + 1, int2bytes(j)).rest

And obtained the following new goals

Proof step 11:
# int2bytes(j) = i→n(i) + 1, 0 < i, j + 2 ^ (i * 8 - 1) < 0, 0 < j + 2 ^ (i * 8), 0 < 2 ^ (i * 8) + j, j < 0 ⊦ j = 0, bits2bytes(int2bits(j)) = i2b(~1) ' + fix(i→n(i) + 1, int2bytes(j)).rest
Proof step 62:
0 < i, j + 2 ^ (i * 8 - 1) < 0, 0 < j + 2 ^ (i * 8), 0 < 2 ^ (i * 8) + j, j < 0 ⊦ # int2bytes(j) = i→n(i) + 1, j = 0, bits2bytes(int2bits(j)) = i2b(~1) ' + fix(i→n(i) + 1, int2bytes(j)).rest

Rule argument

fma: # int2bytes(j) = i→n(i) + 1

Additional information

Used formulas: # int2bytes(j) = i→n(i) + 1
