Number precision below 10^-15

[CPTI1994]

I am using Math cad 13. The results of any calculations containing terms that are below 10^-15 are displayed as zero unless the precision is set to 17 digits. Any way of displaying three digits of precision using terms containing values less than 10^-15?

You need to set the zero tolerance.

It is worth doing that in your template as a global setting (when not inside a region). Then all results will give a value, even when below ~10^-15

Hi Philip,

Your suggestion worked perfectly! Thanks for responding to my message.

Click on a blank area of the worksheet. Go to "Format", "Result", "Tolerance", and set the zero tolerance to a bigger number. All subsequently displayed results will be OK.
