Proof step 4 from proof int2bytes-byte-neg (previous step)

~256 < i, i < ~128, i < 0 ⊦ bits2bytes(int2bits(i)) = i2b(~1) ' + i2b(i) '

User applied rule cut formula

And obtained the following new goals

Proof step 5:
# int2bits(i) = 9, ~256 < i, i < ~128, i < 0 ⊦ bits2bytes(int2bits(i)) = i2b(~1) ' + i2b(i) '
Proof step 30:
~256 < i, i < ~128, i < 0 ⊦ # int2bits(i) = 9, bits2bytes(int2bits(i)) = i2b(~1) ' + i2b(i) '

Rule argument

fma: # int2bits(i) = 9

Additional information

Used formulas: # int2bits(i) = 9
