# decimal-behavior

A decimal-behavior element that provides ceil, round, floor, format and decimalAdjustemnt methods. 

Decimal adjustment of a number implementation is taken from Mozilla Developer Network: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/round.

API documentation and live demo can be found on the component page

## Installation

Install using bower

    bower i decimal-behavior -S

Import the behavior

    

Inlude the behavior in your web component

    behaviors: [DecimalBehavior]

## Example

```html

  

    

      :host {

        display: inline-block;

      }

    

    
decimal-behavior

    
round: [[formatNumber(3.125, 2)]]
            

    
floor: [[formatNumber(3.1415, 3, 'floor')]]
  

    
ceil : [[formatNumber(3.14151, 4, 'ceil')]]

  

  

    Polymer({

      is: 'x-decimal-behavior',

      behaviors: [DecimalBehavior]

    });

  


```

## Methods

### round(value, exp)

Decimal adjustment of a number using the round method.

* value: The number to be adjusted

* exp: The exponent (the 10 logarithm of the adjustment base). -1 = round to 1 decimal

 

### floor(value, exp)

Decimal adjustment of a number using the floor method.

* value: The number to be adjusted

* exp: The exponent (the 10 logarithm of the adjustment base). -1 = round to 1 decimal

### ceil(value, exp)

Decimal adjustment of a number using the ceil method.

* value: The number to be adjusted

* exp: The exponent (the 10 logarithm of the adjustment base). -1 = round to 1 decimal

### formatNumber(value, decimals, type)

Adjusts and formats the passed value to the specified number of decimals using the passed adjustment type. 

The toFixed function is used to  cut off the String representation.

* value: The number to be adjusted

* decimals: The number of decimals (is converted into an exponent). Example 1 = 1 decimal position

* type: The adjustment type: round, floor or ceil. round is set as default.

### decimalAdjust(type, value, exp)

Decimal adjustment of a number.

Original implementation from Mozilla Developer Network: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/round

* type: The adjustment type: round, floor or ceil

* value: The number to be adjusted

* exp: The exponent (the 10 logarithm of the adjustment base). -1 = round to 1 decimal
