step
fun <T : ExpressionValue> step(input: Expression<FloatValue>, fallback: Expression<T>, vararg stops: Pair<Number, Expression<T>>): Expression<T>(source)
Produces discrete, stepped results by evaluating a piecewise-constant function defined by pairs of input and output values (stops). Returns the output value of the stop just less than the input, or the fallback if the input is less than the first stop.
Example:
step(zoom(), const(0), 10 to const(2.5), 20 to const(10.5))Content copied to clipboard
returns 0 if the zoom is less than 10, 2.5 if the zoom is between 10 and less than 20, 10.5 if the zoom is greater than or equal 20.
