Arrays with decimal numbers

Luciano Tresto
Posted 10 years ago

Hello,

I wish to know if it´s possible to use decimal numbers in arrays. The code I have written is the next:

Manipulate[

 Array[# &, a],

 {a, 0, 10}
 ]

enter image description here

With whole numbers, I have no problem. Are there any solution??

Thank you very much.

Hello Marco,

Thank you for your response.

I would like to obtain an array like...{0, 0.2, 1.3, 2.6, 3, 4.8....}, every number, whole or decimal number.

Is it possible?

What should the array be based on? I don't see any logical in the sequence: {0, 0.2, 1.3, 2.6, 3, 4.8....}

There isn't a specific sequence. I refer to any decimal number. I want the array contains decimal numbers and show them, not only whole numbers.

Table[Round[RandomReal[10], 0.01], 7]
{8.17, 1.11, 7.9, 1.88, 2.41, 0.66, 5.42}

Or, sticking to the Array function:

Round[Array[RandomReal, 7, {10}], 0.01]
{8.17, 1.23, 9.47, 2.44, 3.38, 0.99, 8.68}

Hi,

I do not really understand what you want to achieve. Do you mean something like this?

Manipulate[Array[# &, a], {a, 0, 10, 1}]

Cheers,

Marco
