Enter a large number like 15 or 20 so that more digits are displayed to see the non-zero (or non-one) result. That typically works.</P> Wed, 08 Jun 2022 01:11:57 GMT Dan_Obermiller 2022-06-08T01:11:57Z https://community.jmp.com/t5/Discussions/When-does-JMP-round-probability-to-1-or-0/m-p/502135#M73568 <P>This may be posted somewhere but I can't find it. I have used various distribution functions to determine the probability of a given number in a distribution for many different applications. Sometimes the value is so far off the distribution that the functions return 0 or 1. I was wondering what is the limit where JMP stops and rounds to 0 or 1. That way I can present it as a probability less than what ever that tiny number is and not just say 0.&nbsp;</P> Sat, 10 Jun 2023 23:49:12 GMT https://community.jmp.com/t5/Discussions/When-does-JMP-round-probability-to-1-or-0/m-p/502135#M73568 shaunhunter 2023-06-10T23:49:12Z https://community.jmp.com/t5/Discussions/When-does-JMP-round-probability-to-1-or-0/m-p/502262#M73569 <P>I don't know when the rounding occurs, but when you encounter a 1 or a 0, double-click that value and change the formatting from Best to Fixed Decimal.
