Proof step 7 from proof bytes2int-2-le-32767 (previous step)

32768 ≤ band(b2i(by1), 255) + 256 * b2i(by), 0 < band(b2i(by1), 255) + 256 * b2i(by), 0 ≤ band(b2i(by1), 255) + 256 * b2i(by) ⊦

User applied rule cut formula

And obtained the following new goals

Proof step 8:
32768 = 256 * 128, 32768 ≤ band(b2i(by1), 255) + 256 * b2i(by), 0 < band(b2i(by1), 255) + 256 * b2i(by), 0 ≤ band(b2i(by1), 255) + 256 * b2i(by) ⊦

Rule argument

fma: 32768 = 256 * 128

Additional information

Used formulas: 32768 = 256 * 128
