Clash Royale CLAN TAG #URR8PPP up vote 3 down vote favorite Consider the following list list=0,0,0,10^-18,10^-15,10^-12,10^-10,1,1 How can I apply a threshold on the list that will give a lower bound for the values. For example ApplyThreshold[list,10^-12]; will yield an outcome of 10^-12,10^-12,10^-12,10^-12,10^-12,10^-12,10^-10,1,1 and ApplyThreshold[list,10^-9]; will yield an outcome of 10^-9,10^-9,10^-9,10^-9,10^-9,10^-9,10^-9,1,1 list-manipulation share | improve this question asked Aug 26 at 9:20 jarhead 689 4 12 add a comment  |  up vote 3 down vote favorite Consider the following list list=0,0,0,10^-18,10^-15,10^-12,10^-10,1,1 How can I apply a threshold on the list that will give a lower bound for the values.

I know it's been asked but as a new programer I find it hard to understand. an example would be very appreciated also. programming share | improve this question edited Aug 26 at 9:54 asked Aug 26 at 9:05 rafi shoval 11 2 closed as off-topic by Juraj, sempaiscuba, Greenonline, VE7JRO, per1234 Aug 27 at 0:30 This question appears to be off-topic.
