How to come out with a random number from a field that have text and numbers.

[webuxer]

Hi I need help on excluding text from a cell and come out with a random number up to 3 numbers. Please see the attached image;

If you notice in column D there is text and a number that starts with a decimal, for example on the first row is .437 the next row is .215 next row is .63 etc... Is there a way to come out with a random number mixing it up to 3 digits and output those number on column "E"? Im only interested in filtering and coming out with the random number i mentioned .437 .215 .63 etc... not the +/-.010in.
There is no right or wrong number, i just need to come out with random number using up to 3 numbers up.
Maybe for .437 three numbers up could be .440 for the next row .215 maybe a number up .216..etc..

Hope there is a way to do this, my excel file is too long to type a number manually.
Thanks in advanced

Is this what you are looking for?

E1 --> =TEXT(RANDBETWEEN(1,3)/1000+MID(D1,SEARCH(".",D1),4),"0.000")

Fill down as needed.
