convert float raster to integer raster.

I have converted a float raster to integer raster with band math. it appears white in snap. I was used the inrange int() expression.

       So please guide me how to convert float raster in integer raster.

If you simply need to round, e.g. 15.7492 (float) to 16 (int), you can use the Band Maths and the round() operator, which makes each pixel the next highest value:

If you want to change the data type of your product, you can use the Raster > Data Conversion > Convert Datatype and make an integer out of your input image, for example 8 bit scaled between 0 and 255.
