Find best fit of number

[OnlyOne]

Hello,
can someone help me with this problem:

I have a numeric-double-control as input.
Then i have a numeric-double-array-constant with ~10 numbers.

The output should be one of the constant-numbers which is the nearest to the input-number.

For example:
input: 2.7
constant-array: 0.1 / 0.7 /2.1 / 3 / 5.5 / 9

The the ouput should be: 3

Thanks for your help

Hi NewOne:

I think you want us to solve your exercise.

Try explaining the way you think it can be done, and if it is not correct someone can tell you where the problem is.

Have you tried to substract them and find de lowest in absolute?

Hello Aitortxo,
I already did it like you said but i thought there woul be an easier/faster way to do it than searching an array.
