Swashbuckle wraps number examples with double quotes from VS XML comments - asp.net-core

Question

I have a class representing a body for an endpoint, in that class is an Amount property, it looks like this:
/// <summary>
/// The transaction amount; it must be greater than 0
/// </summary>
/// <example>1.23</example>
[JsonProperty("Amount")]
[Required]
public decimal Amount { get; set; }
The problem I'm having is that when Swashbuckle generates the JSON for this Request body example, it ends up wrapping the Amount value with double quotes like this:
{
"Amount": "1.23"
}
I want it to look like a number, like this:
{
"Amount": 1.23
}
If I give no XML example tag, the Request Body example generated in the SwaggerUI is just 0.0 with no double quotes, like this:
{
"Amount": 0.0
}
The portion of the XML comments that is generated from this example doesn't have quotes:
<member name="P:MyAPI.Models.SaleRequest.Amount">
<summary>
The transaction amount; it must be greater than 0
</summary>
<example>1.23</example>
</member>
But the JSON generated from Swashbuckle does:
"SaleRequest": {
"required": [
"Amount"
],
"type": "object",
"properties": {
"Amount": {
"format": "decimal",
"description": "The transaction amount; it must be greater than 0",
"type": "number",
"example": "1.23"
}
}
}
Is there a way I can tell Swashbuckle not to wrap this XML example tag for a number property with double quotes? I've been searching for a while and can't find anything. I've tried c.MapType<decimal>(() => new Schema { Type = "number", Format = "decimal" }); from another post when configuring swagger but that didn't change anything. I didn't see any attributes I could apply to the property in the source code either. I'm using Swashbuckle 4.0.1
