 * @param {number} value - The initial number value.
 * @param {Object} [options] - The options to constrain the number.
 * @param {number} [options.min=-Infinity] - The minimum allowed value.
 * @param {number} [options.max=Infinity] - The maximum allowed value.
 * @param {number} [options.step=1] - The step size for increment/decrement operations.
 * @returns {number} The number value, constrained to the specified range.
