For example, the function
[tex]f\left( x \right) = \left\{ {\begin{array}{*{20}c}
{1:x > 0} \\
{0:x = 0} \\
{ - 1:x < 0} \\
\end{array} } \right.[/tex]
is known as the sign function, usually represented as sgn x.
However, is there a specific name for the function
[tex]f\left( x \right) = \left\{ {\begin{array}{*{20}c}
{1:x > 0} \\
{ - 1:x \leqslant 0} \\
\end{array} } \right. [/tex]
?
