Problem in using Math(abs)

[ShiuliPervin]

I have a raster with Pixel values ranges from High : 0,187477 to Low : -1,14927. I want to avoid negetive Value without altering the value of Pixel. I tried to use math(abs). But the out raster give the pixel values ranges from High:1.14927 and low:0.0379639 that are not same as original. Could anyone tell me How it works?

Thanks:-)

the low value could change if there was a -0.0379639  in the data set
