how to convert a exponentail to whole number

hai

i want to convert an matrix of exponential values to whole numbers

for example 3.6889e-005 -0.00017216 2.3815e-005 -0.00010904 -0.00023487 -0.00013938 8.2785e-005

What is the wanted output? E.g. the "whole number" for 3.6889e-005: Is it 0 or 1 or -5?

i want some value in negative or 0 what is the command used for converting the entire matrix of exponential values to whole numbers

[Jan]

Please, kanagapushpavalli, post an example. "Some value in negative or 0" is not precise enough to understand, what you are loocking for. Repeating the question is not helpful, if I told you already, that I cannot understand the problem.

Perhaps you want round(log(x))??

[ramya raj]

i can't understand what type of example you want

@kanagapushpavalli: an easier nickname no eh?

Anyways, all of your numbers are a fraction of a unit, i.e. you cannot convert them to integers without applying a transformation.

In brief, Jan is asking: if you have 0.00001 how do you want it to become an integer?

@kanagapushpavalli: If your input is 3.6889e-005, what number do you want to get as output?

It is sometimes frustrating if the authors do not post a very tiny but necessary detail, which would allow a correct answer.

There are several possible solutions, because the question is not equivocal:

• floor(x)
• ceil(x)
• fix(x)
• round(x)
• round(log10(x))

Look in the help text of these function to learn how to use them. If you specify the wanted output, a more precise help is possible.
