Proof step 5 from proof byte-size-01 (previous step)

32768 < 2 ^ (n→i(# int2bits(b2i(by))) - 1) ⊦ 128 < 2 ^ (n→i(# int2bits(b2i(by))) - 1), # int2bits(b2i(by)) = 1

User applied rule cut formula

And obtained the following new goals

Proof step 6:
128 < 32768, 32768 < 2 ^ (n→i(# int2bits(b2i(by))) - 1) ⊦ 128 < 2 ^ (n→i(# int2bits(b2i(by))) - 1), # int2bits(b2i(by)) = 1

Rule argument

fma: 128 < 32768
