 * Curried function to parse strings to numbers based on different radixes.
 *
 * @category Number
 * @remarks
 * Parses a `string` to a `number` with the given `radix`, returning `undefined`
 * instead of `NaN` if it fails.
 * @example
 * ```typescript
 * const parseDecimal = parseInteger(10);
 *
 * parseDecimal("101"); // 101
 * parseDecimal("101.5"); // 101
 * parseDecimal("invalid"); // undefined
 * ```
 * @see {@link undefineNaN}
 *
 * @param radix Radix to use for parsing (`16` for hexadecimal, `10` for decimal, and so on).
 * @returns Curried function with `radix` in context.
