almost-equal
|
||
|
|
============
|
||
|
|
Checks when two floats are almost equal.
|
||
|
|
|
||
|
|
Use
|
||
|
|
===
|
||
|
|
First install using npm:
|
||
|
|
|
||
|
|
npm install almost-equal
|
||
|
|
|
||
|
|
Then use as follows:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var almostEqual = require("almost-equal")
|
||
|
|
|
||
|
|
var a = 100
|
||
|
|
, b = 100 + 1e-12
|
||
|
|
|
||
|
|
//Check if a == b up to float precision
|
||
|
|
console.log(almostEqual(a, b, almostEqual.FLT_EPSILON, almostEqual.FLT_EPSILON))
|
||
|
|
|
||
|
|
//Check if a == b up to double precision
|
||
|
|
console.log(almostEqual(a, b, almostEqual.DBL_EPSILON, almostEqual.DBL_EPSILON))
|
||
|
|
```
|
||
|
|
|
||
|
|
### `almostEqual(a, b[, absoluteTolerance [, relativeTolerance]])`
|
||
|
|
Checks if two floats are within the given tolerances of one another using the formula:
|
||
|
|
|
||
|
|
|a - b| < max(absoluteTolerance, min(|a|, |b|) * relativeTolerance)
|
||
|
|
|
||
|
|
* `a` and `b` are the two numbers to comapre
|
||
|
|
* `absoluteTolerance` is a fixed minimal tolerance (set to 0 to ignore)
|
||
|
|
* `relativeTolerance` is a tolerance that scales with a/b (set to 0 to ignore)
|
||
|
|
|
||
|
|
**Returns** `true` if `a` and `b` are approximately equal.
|
||
|
|
|
||
|
|
If tolerance argument is omitted, `almostEqual.DBL_EPSILON` value is used by default.
|
||
|
|
|
||
|
|
### `almostEqual.FLT_EPSILON`
|
||
|
|
Floating point (32-bit) epsilon
|
||
|
|
|
||
|
|
### `almostEqual.DBL_EPSILON`
|
||
|
|
Double precision (64-bit) epsilon
