Proof step 1 from proof bint-is-cast-01 (conclusion)

⊦ i2bi(i) = i2bi(cast(32, i))

User applied rule cut formula

And obtained the following new goals

Proof step 2:
bi2i(i2bi(i)) = bi2i(i2bi(cast(32, i))) ⊦ i2bi(i) = i2bi(cast(32, i))
Proof step 4:
⊦ bi2i(i2bi(i)) = bi2i(i2bi(cast(32, i))), i2bi(i) = i2bi(cast(32, i))

Rule argument

fma: bi2i(i2bi(i)) = bi2i(i2bi(cast(32, i)))

Additional information

Used formulas: bi2i(i2bi(i)) = bi2i(i2bi(cast(32, i)))
