Sign
(Built-in Mathematica Symbol) Sign[x] gives -1, 0, or 1 depending on whether x is negative, zero, or positive.
Slider
(Built-in Mathematica Symbol) Slider[x] represents a slider with setting x in the range 0 to 1. Slider[Dynamic[x]] takes the setting to be the dynamically updated current value of x, with the value of x ...
