默认 ansi 9standards0 code issues - which way does the decima

ansi which way does the decima
i have forgotten which way the decimal point advances when the number reads x.xxe+.008 as an example.
thank you in advance
check out our whitepaper library.
i'm not sure what you mean and i've never seen the example you used (x.xxe+.008).
i've seen x.xxe8 which is xxx,000,000 written out in full (decimal moves to the right) or x.xxe-8 which is 0.0000000xxx where the decimal moves to the left (should be 7 zeros in there if i can see right on this screen).
of course, you can have an exponent to a fractional power but you don't just move the decimal place in that case to get to the answer.
for example, 2e0.005 is 1.0035.
i might be wrong, but i think that the x.xxe0.008 format means
xxx * 10^0.008
and 2e0.005 means
2*10^0.005 = 2*1.01157 = 2.02315.....
oops
the first number in my previous post should be
x.xx * 10^0.008
