Question 1199884
<font color=black size=3>
"sign function" is also known as "signum function".


In my opinion, the name "signum" is better than "sign" because the second option sounds identical to "sine".


There are 3 cases with the signum function.<ol type="A"><li>If the input is positive, then output = 1</li><li>If the input is 0, then output = 0</li><li>If the input is negative, then output = -1</li></ol>We want to evaluate f(237).
The input is 237 and it is positive. 
We go for scenario A.


f(237) = 1
