# Min Safe Integer > Minimum safe [double-precision floating-point][ieee754] integer.
## Usage ```javascript var FLOAT64_MIN_SAFE_INTEGER = require( '@stdlib/constants/float64/min-safe-integer' ); ``` #### FLOAT64_MIN_SAFE_INTEGER The minimum [safe][safe-integers] [double-precision floating-point][ieee754] integer. ```javascript var bool = ( FLOAT64_MIN_SAFE_INTEGER === -9007199254740991 ); // returns true ```
## Examples ```javascript var randu = require( '@stdlib/random/base/randu' ); var round = require( '@stdlib/math/base/special/round' ); var pow = require( '@stdlib/math/base/special/pow' ); var FLOAT64_MIN_SAFE_INTEGER = require( '@stdlib/constants/float64/min-safe-integer' ); var min; var x; var i; min = -pow( 2.0, 55 ); for ( i = 0; i < 100; i++ ) { x = round( randu() * min ); if ( x < FLOAT64_MIN_SAFE_INTEGER ) { console.log( 'Unsafe: %d', x ); } else { console.log( 'Safe: %d', x ); } } ```
