Earnings Per Share [Text Block] | NOTE R —EARNINGS PER SHARE (EPS) The Company ’s basic EPS is calculated using net income (loss) available to common shareholders and the weighted-average number of shares outstanding during the reporting period. Diluted EPS includes the effect from potential issuance of common stock, such as stock issuable pursuant to the exercise of stock options and warrants and the assumed conversion of preferred stock. The reconciliation of the numerator of the basic and diluted EPS calculations, due to the inclusion of preferred stock dividends was as follows for the following fiscal years ended December 31:
|  | 2017 |  |  | 2016 |
Basic Numerator: |  |  |  |  |  |  |  |
Loss from continuing operations |  | $ | (4,275,338 | ) |  | $ | (4,189,704 | )
Convertible preferred stock dividends |  |  | (769,158 | ) |  |  | (802,500 | )
Net loss available to common stockholders (basic and diluted EPS) |  | $ | (5,044,496 | ) |  | $ | (4,992,204 | )
