The obvious observation is that ‘x’ is going to be less than 10 from the initial iteration through how many iterations it takes to be essentially equivalent to -Infinity.

so what is the suggested answer to avoid this loop (x=1:1:10) ?

Add 1 instead of subtract 1.

Yes. Open up a new question and we can help.

For my part, to an extent, although I’ve not done anything with them since graduate school (when we rode sauropods). However -Inf is still -Inf reagrdless of the base it is calcualted in. It just takes a different form.

ok so for example the question is that in 6 bit system which calculates negative numbers , they give us the binary form for example 100000 and we should write what number it represents
