almost-equal
============
Checks when two floats are almost equal.
Use
===
First install using npm:

Checks if two floats are within the given tolerances of one another using the formula:

Floating point (32-bit) epsilon

Double precision (64-bit) epsilon

`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.
