Function unequal
Test whether two values are unequal.
The function tests whether the relative difference between x and y is larger than the configured epsilon. The function cannot be used to compare values smaller than approximately 2.22e-16.
For matrices, the function is evaluated element wise. In case of complex numbers, x.re must unequal y.re, or x.im must unequal y.im.
Values null
and undefined
are compared strictly, thus null
is unequal
with everything except null
, and undefined
is unequal with everying
except. undefined
.
Syntax
unequal(x, y)
Parameters
Parameter | Type | Description |
---|---|---|
x |
number | BigNumber | Fraction | boolean | Complex | Unit | string | Array | Matrix | undefined | First value to compare |
y |
number | BigNumber | Fraction | boolean | Complex | Unit | string | Array | Matrix | undefined | Second value to compare |
Returns
Type | Description |
---|---|
boolean | Array | Matrix | Returns true when the compared values are unequal, else returns false |
Examples
unequal(2 + 2, 3); // returns true
unequal(2 + 2, 4); // returns false
var a = unit('50 cm');
var b = unit('5 m');
unequal(a, b); // returns false
var c = [2, 5, 1];
var d = [2, 7, 1];
unequal(c, d); // returns [false, true, false]
deepEqual(c, d); // returns false
unequal(0, null); // returns true
