/**
 * Separates a number at its highest place value
 * @param  {string|number} input Value to separate
 * @returns [number, number] [primary value (highest place), remainder]
 * @example mathSeparator(1250); // [1000, 250]
 * @description
 * This function takes a number and separates it into two parts:
 * 1. The highest place value (e.g., 1000 for 1250)
 * 2. The remainder (e.g., 250 for 1250)
 * It also handles decimal numbers appropriately
