+ * @function clampNumber
+ * @description Clamps a number between a minimum and maximum value.
+ *   If the number is less than min, returns min.
+ *   If the number is greater than max, returns max.
+ *   Otherwise returns the number itself.
+ * @param {number} num - The number to clamp
+ * @param {number} min - The minimum value
+ * @param {number} max - The maximum value
+ * @returns {number} - The clamped number
+ * @see https://en.wikipedia.org/wiki/Clamping_(graphics)
+ * @example clampNumber(5, 1, 10) => 5
+ * @example clampNumber(-5, 1, 10) => 1
+ * @example clampNumber(15, 1, 10) => 10
