Reply To: Absolute value
I apologize for the delay in responding to your question. I have been out of town and neglected to get someone to fill in for me.
I don't know what your absolute value symbol looks like in print. Usually absolute value is indicated by vertical bars enclosing the number or letter. In that case you would use the braille vertical bar (1256) If your symbol is something other than a vertical bar, please let me know.
