Serializing Double Value To Json String

I'm trying to serialize a double value 1.0 into JSON value 1.0. However, the following code outputs 1 instead of 1.0: var jsSerializer = new JavaScriptSerializer(); var json = jsSe

Solution 1:

It doesn't matter. All numbers in Javascript are floating point numbers (IEEE 754 double precision, to be exact): whether you say

• var x = 1 ;
• var x = 1.0 ;
• { x : 1 }

the net result is the same: x is a floating point number with a value of 1.

Solution 2:

If you need a specific text format for the value, you should serialize it as a string. JSON isn't about text representation, it's about accurately serializing and deserializing values. It only has one "Number" data type; if integer values lack a ".0" at the end, that's either because the specification says to do it that way or the specification leaves it to the implementation to decide. The value of saving 2 characters per integer is probably significant in many applications.
