I am using Raster Calcuator in ModelBuilder with ArcMap 10.5.
I used Get Raster Properties to extract Standard Deviation and Mean from a previously calculated raster.
I would like to use Raster Calc again to create a raster where
raster = (mean + 3*(SD)) or (mean -3*(SD)). I attempted to use a Con statement with a boolean or (|) operator. Con statement I am using is as follows:
Con(("difference_mean_normalized_.tif" < (float(%Mean%) - 3 * (float(%Standard Deviation%)))) | ("difference_mean_normalized_.tif" > (float(%Mean%) + 3 * (float(%Standard Deviation%)))), 0, 1)
difference_mean_normalized_.tif is my output raster.
This fails and I am getting a 000539 Error:

Failed to execute (Raster Calculator (3)).
Some notes: I double-click or drag the variables in from the list in Raster Calc, and "float" is automatically added to the expression for each variable. I manually type in the output raster name. I have tried wrapping the raster name with the % symbol as well, although this is not shown in the screenshot. Also, my original bands were integer, and I had to use the float() operator to convert.
How do I use Raster Calc in ModelBuilder to create a raster +/- 3SD from mean?
