round
(value,places,increment)
Defined by dojo/number
Rounds to the nearest value with the given number of decimal places, away from zero
Rounds to the nearest value with the given number of decimal places, away from zero if equal. Similar to Number.toFixed(), but compensates for browser quirks. Rounding can be done by fractional increments also, such as the nearest quarter. NOTE: Subject to floating point errors. See dojox/math/round for experimental workaround.
Parameter  Type  Description 

value  Number 
The number to round 
places  Number  Optional
The number of decimal places where rounding takes place. Defaults to 0 for whole rounding. Must be nonnegative. 
increment  Number  Optional
Rounds next place to nearest value of increment/10. 10 by default. 
Returns: number
>>> number.round(0.5)
1
>>> number.round(162.295, 2)
162.29 // note floating point error. Should be 162.3
>>> number.round(10.71, 0, 2.5)
10.75
