# interpolate

Produces continuous, smooth results by interpolating between pairs of input and output values ("stops"). The `input`

may be any numeric expression (e.g., `["get", "population"]`

). Stop inputs must be numeric literals in strictly ascending order. The output type must be `number`

, `array<number>`

, or `color`

.

Interpolation types:

`["linear"]`

: Interpolates linearly between the pair of stops just less than and just greater than the input.`["exponential", base]`

: Interpolates exponentially between the stops just less than and just greater than the input.`base`

controls the rate at which the output increases: higher values make the output increase more towards the high end of the range. With values close to 1 the output increases linearly.`["cubic-bezier", x1, y1, x2, y2]`

: Interpolates using the cubic bezier curve defined by the given control points.
