Specs

calculate(integer(), integer()) :: range()

Creates a new Easing.Range struct from a desired duration and target fps

• duration_in_ms - total duration of the animation, only accepts Integer
• fps - target frames per second of the animation, only accepts Integer

Examples:

iex> Easing.Range.calculate(1000, 1)
%Easing.Range{first: 0, last: 1, step: 1.0}

Specs

new(number(), number(), number()) :: range()

Convenience function for creating a new Easing.Range struct

• first: represents the starting % of the range. Value should be: value >= 0 and < 1
• last: represents the ending % of the range. Value should be: value > 0 and <= 1
• step: value representing what the incremental value is between first and last. Can represent

Specs

size(range()) :: integer()

Returns the size of the Easing.Range

Sizes are inclusive across a range. So a range from 0 - 1 with a step of 0.1 will have 11 values, not 10 because the 0 value is included in that result.

Examples:

iex> Easing.Range.calculate(1000, 60) |> Easing.Range.size()
61
