Replacing the first 0 with a number
Hi,

Appreciate any help in advance ;-)

There are some numbers between 0 and 1, 0 not included: .2500, .3333, .5000, .6666, .7500, 1.000

How to replace the first 0 ( after the dot ) with a number, say, if the number is 3:
.2500 will be .2530
.5000 will be .5300
.7500 will be .7530

If there is no 0, the number will be appended to the end:
.3333 will be .33333
.6666 will be .66663

If the number is double digit number ( or more ), say 34, then
.2500 will be .2534
.5000 will be .5340
.7500 will be .7534

If there is no 0, the number will be appended to the end:
.3333 will be .333334
.6666 will be .666634


I'm thinking a function accepting two parameters, the first one will be the number needs to be modified ( eg. .2500, or .3333 ), the second one will be the positive number to add ( eg. 3, or 34, or 334, etc, not zero )

Any ideas, or examples will be very much welcomed.

Regards
