Fibonacci Number
Maximum safe nth Fibonacci number when stored in double-precision floating-point format.
Usage
var FLOAT64_MAX_SAFE_NTH_FIBONACCI = require( '@stdlib/constants/float64/max-safe-nth-fibonacci' );
FLOAT64_MAX_SAFE_NTH_FIBONACCI
The maximum safe nth Fibonacci number when stored in double-precision floating-point format.
var bool = ( FLOAT64_MAX_SAFE_NTH_FIBONACCI === 78 );
// returns true
