{{alias}}( x[, continuity] )
Evaluates the Heaviside function.
The `continuity` parameter may be one of the following:
- 'half-maximum': if `x == 0`, the function returns `0.5`.
- 'left-continuous': if `x == 0`, the function returns `0`.
- 'right-continuous': if `x == 0`, the function returns `1`.
By default, if `x == 0`, the function returns `NaN` (i.e., the function is
discontinuous).
Parameters
----------
x: number
Input value.
continuity: string (optional)
Specifies how to handle `x == 0`. By default, if `x == 0`, the function
returns `NaN`.
Returns
-------
y: number
Function value.
Examples
--------
> var y = {{alias}}( 3.14 )
1.0
> y = {{alias}}( -3.14 )
0.0
> y = {{alias}}( 0.0 )
NaN
> y = {{alias}}( 0.0, 'half-maximum' )
0.5
> y = {{alias}}( 0.0, 'left-continuous' )
0.0
> y = {{alias}}( 0.0, 'right-continuous' )
1.0
