Concept:
The sign function, also known as the signum function (from the Latin signum, which means "sign"), is a strange mathematical function that extracts the sign of a real integer. The sign function is frequently written as sgn in mathematical expressions. This function is commonly referred to as the signum function to avoid confusion with the sine function.
Given:
Value of sgn(-3.2) + sgn(0)
Find:
we have to find value of sgn(-3.2) + sgn(0)
Solution:
sgn(x) is defined in three values
The Signum function returns a number's sign.
Negative numbers are represented by -1, zero by zero, and positive numbers by +1.
sgn(x) = -1 where x < 0
sgn(x) = 0 where x = 0
sgn(x) = 1 where x >0
=> sgn (-3)= -3
= -3 < 0
so, sgn(-3) = -1
=> Sgn(0)= 0
sum = -1+0
= -1
Therefore, the value of sgn(-3.2)+sgn(0) = -1
