A simple TypeScript starter kit using Bun.

 * Check if the string is Decimal

 * @param str - The string to check
 * @param options - Options object
 * @returns True if the string matches the validation, false otherwise
 *>;

export default function isDecimal(str: string, options: Partial<DecimalValidatorOptions>): boolean {

  const mergedOptions = merge(options, default_decimal_options) as DecimalValidatorOptions
  if (mergedOptions.locale in decimal) {
    return !includes(blacklist, str.replace(/ /g, '')) && decimalRegExp(mergedOptions).test(str)
  }
  throw new Error(`Invalid locale '${mergedOptions.locale}'`)
};
