# isAlmostEqual
22+
23+
> Test if two arguments are approximately equal within a specified number of ULPs (units in the last place).
24+
25+
<section class="usage">
26+
27+
## Usage
28+
29+
```javascript
30+
var isAlmostEqual = require( '@stdlib/assert/is-almost-equal' );
31+
```
32+
33+
#### isAlmostEqual( a, b, maxULP )
34+
35+
Tests if two arguments are approximately equal within a specified number of ULPs (units in the last place).
36+
37+
```javascript
38+
var EPS = require( '@stdlib/constants/float64/eps' );
39+
40+
var bool = isAlmostEqual( 1.0, 1.0+EPS, 1 );
41+
// returns true
42+
43+
bool = isAlmostEqual( '', '', 0 );
44+
// returns true
45+
46+
bool = isAlmostEqual( {}, {}, 1 );
47+
// returns false
48+
```
49+
50+
The function returns `false` if either input value is `NaN` or in the case of [complex numbers][@stdlib/complex], if either the real or imaginary component is `NaN`.
51+
52+
```javascript
53+
var bool = isAlmostEqual( NaN, 1.0, 1 );
54+
// returns false
55+
56+
bool = isAlmostEqual( NaN, NaN, 1 );
57+
// returns false
58+
59+
var Complex128 = require( '@stdlib/complex/float64/ctor' );
60+
var z1 = new Complex128( NaN, 3.0 );
61+
var z2 = new Complex128( 1.0, 3.0 );
62+
63+
bool = isAlmostEqual( z1, z2, 1 );
64+
// returns false
65+
66+
z1 = new Complex128( NaN, NaN );
67+
z2 = new Complex128( NaN, NaN );
68+
69+
bool = isAlmostEqual( z1, z2, 1 );
70+
// returns false
71+
```
72+
73+
The function does not distinguish between `-0` and `+0`, treating them as equal.
74+
75+
```javascript
76+
var bool = isAlmostEqual( 0.0, -0.0, 0 );
77+
// returns true
78+
79+
var Complex128 = require( '@stdlib/complex/float64/ctor' );
80+
var z1 = new Complex128( 0.0, 0.0 );
81+
var z2 = new Complex128( -0.0, -0.0 );
82+
83+
bool = isAlmostEqual( z1, z2, 0 );
84+
// returns true
85+
```
