isAlmostSameArray

Test if two arguments are both generic arrays and contain respective elements which are approximately the same value within a specified number of ULPs (units in the last place).

Usage

var isAlmostSameArray = require( '@stdlib/assert/is-almost-same-array' );

isAlmostSameArray( v1, v2, maxULP )

Tests if two arguments are both generic arrays and contain respective elements which are approximately the same value within a specified number of ULPs (units in the last place).

var EPS = require( '@stdlib/constants/float64/eps' );

var x = [ 1.0, 2.0 ];
var y = [ 1.0+EPS, 2.0 ];

var bool = isAlmostSameArray( x, y, 0 );
// returns false

bool = isAlmostSameArray( x, y, 1 );
// returns true

bool = isAlmostSameArray( x, [ -1.0, 2.0 ], 1 );
// returns false

Examples

var isAlmostSameArray = require( '@stdlib/assert/is-almost-same-array' );

var x = [ 1.0, 2.0, 3.0 ];
var y = [ 1.0, 2.0, 3.0 ];
var out = isAlmostSameArray( x, y, 0 );
// returns true

x = [ -0.0, 0.0, -0.0 ];
y = [ 0.0, -0.0, 0.0 ];
out = isAlmostSameArray( x, y, 0 );
// returns false

x = [ NaN, NaN, NaN ];
y = [ NaN, NaN, NaN ];
out = isAlmostSameArray( x, y, 0 );
// returns true
