How can I get asp.net mvc to recognize decimals in json?

In my .net application I'm using System.Web.Mvc 5.2.3.0. My client is posting up json with the content-type: 'application/json'

{From: "EUR", To: "USD", Rate: 0.00001}

By the time my controller receives this 

[HttpPut(), Route("/ExchangeRate/{exchkey}")]
public HttpResponseMessage PutCurrencyExchange(string exchkey, [FromBody()] JObject jsonData)
 {...

The JObject's Rate is a string "1E-05".

I've read about custom converters https://www.newtonsoft.com/json/help/html/N_Newtonsoft_Json_Converters.htm and contract resolvers https://www.newtonsoft.com/json/help/html/CustomContractResolver.htm

I found a number of very old examples for deserializing strongly typed objects. However, I'm hoping I'm just missing a simple configuration change that will allow my controller's JObject to correctly represent the decimal as a decimal. Note: I recognize that if the client stringifies the value, it will parse it correctly. However, I'm not able to dictate that consumers of my endpoints stringify the values first.

I've had better luck with a controller action containing individual parameters rather than from body if you're able to change that
