Converting large value float value to integer using ArcGIS Desktop

I have a raster with 32 bit unsigned values that I want to convert to a polygon shapefile. I ran the raster calculator in ArcGIS to remove the decimals by multiplying by a constant and then running raster calculator again but this time converting to integer.

The output integer values do not match what the values were before converting to an integer. I’m not sure what is happening but by doing it this way will not work especially if its coming up with totally different values.

Clarification

I am running ArcGIS 10.4.1

For example – the raster holds values from 7881.530000 to 53613.300000
Multiplying the raster values by 1000000 because of the 6 decimal places

Converting the raster to integer results in completely different values

Real Example:

Pixel value: 39961.472656

Multiply by Constant: 39961473024.000000 (this number is already different)

Converted to Integer: 1306767360

If the pixel values are much smaller, the results are fine

Example:

Pixel Value: 0.087640

Multiply by Constant: 87640.140625

Converted to Integer: 87640

The end result is to convert to a polygon shapefile where I will add a field and calculate the value to be based on the Integer Value where I divide it by the constant to get back to the original pixel value.
