[![Dependencies][dependencies-image]][dependencies-url]\n\n> Maximum safe [double-precision floating-point][ieee754] integer.\n\n\n## Installation\n\n``` bash\n$ npm install compute-const-max-safe-integer\n```\n\n\n## Usage\n\n``` javascript\nvar MAX_SAFE_INTEGER = require( 'compute-const-max-safe-integer' );\n```\n\n#### MAX_SAFE_INTEGER\n\nThe maximum [safe][safe-integers] [double-precision floating-point][ieee754] integer.\n\n``` javascript\nMAX_SAFE_INTEGER === Math.pow( 2, 53 ) - 1; // 9007199254740991\n```\n\n\n## Examples\n\n``` javascript\nvar round = require( 'math-round' );\nvar pow = require( 'math-power' );\nvar MAX_SAFE_INTEGER = require( 'compute-const-max-safe-integer' );\n\nvar max;\nvar x;\nvar i;\n\nmax = pow( 2, 55 );\nfor ( i = 0; i < 100; i++ ) {\n\tx = round( Math.random() * max );\n\tif ( x > MAX_SAFE_INTEGER ) {\n\t\tconsole.log( 'Unsafe: %d', x );\n\t} else {\n\t\tconsole.log( 'Safe: %d', x );\n\t}\n}\n```\n\nTo run the example code from the top-level application directory,\n\n``` bash\n$ node ./examples/index.js\n```\n\n\n---\n## Tests\n\n### Unit\n\nThis repository uses [tape][tape] for unit tests. To run the tests, execute the following command in the top-level application directory:\n\n``` bash\n$ make test\n```\n\nAll new feature development should have corresponding unit tests to validate correct functionality.\n\n\n### Test Coverage\n\nThis repository uses [Istanbul][istanbul] as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:\n\n``` bash\n$ make test-cov\n```\n\nIstanbul creates a `./reports/coverage` directory. To access an HTML version of the report,\n\n``` bash\n$ make view-cov\n```\n\n\n### Browser Support\n\nThis repository uses [Testling][testling] for browser testing. To run the tests in a (headless) local web browser, execute the following command in the top-level application directory:\n\n``` bash\n$ make test-browsers\n```\n\nTo view the tests in a local web browser,\n\n``` bash\n$ make view-browser-tests\n```\n\n<!-- [![browser support][browsers-image]][browsers-url] -->\n\n\n---\n## License\n\n[MIT license](http://opensource.org/licenses/MIT).\n\n\n## Copyright\n\nCopyright &copy; 2015-2016.
