Question on Mathcad while loops

[aharkness]

When I have a while loop that goes as long as x does not equal 1.0, then it does the operation x = x + .1. The result is an infinite while loop. Why does this happen

[AlanStevens]

Never test for exact equality using reals!  Always do a comparison along the lines of  |x - 1|<10^-6 .

Its better to have a worksheet to see what you actually did.

Maybe you ran into a accuracy problem. Not sure though.

Maybe not :  "while x does not equal 1"

but rather:   " while x is less than 1"
