Usage

var SMALLEST_FLOAT64 = require( 'const-smallest-float64' );

SMALLESTFLOAT64

An object comprised as follows:
{
	'VALUE': 2.2250738585072014e-308,
	'DENORMALIZED': ~4.94e-324
}
Value
Smallest positive normalized double-precision floating-point numberieee754.
SMALLEST_FLOAT64.VALUE === Math.pow( 2, -(1023-1) );
Denormalized
Smallest positive denormalized double-precision floating-point numberieee754.
SMALLEST_FLOAT64.DENORMALIZED === Math.pow( 2, -(1023-1+52) );

Examples

var SMALLEST_FLOAT64 = require( 'const-smallest-float64' );

console.log( SMALLEST_FLOAT64.VALUE );
// returns 2.2250738585072014e-308

console.log( SMALLEST_FLOAT64.DENORMALIZED );
// returns ~4.94e-324
