this is an another solution
(German mnemonic ! U = A)
Code: Select all
U E 1.0
FP M 1.0
SPBN SLT1
UN A 1.0
= A 1.0
SLT1: NOP
and an another
Code: Select all
U E 1.0 // Input
UN M 0.0 // Aux
S M 0.0
U E 1.0
U M 0.1
R M 0.0 // Aux
UN E 1.0
U M 0.0
S M 0.1
UN M 1.0
U M 1.0
R M 0.1
U M 1.0
= A1.0 //Output
