hi,

I want to validate a decimal number with some condition

1. After decimal point , there is only one digit

2. After decimal point ,that one digit will be 5 . eg:- 1.5, 2.5, 33.5 ....like that..

I tried to find out , but only I found the 1st point (

/^[0-9]*(?:\.\d{1})?$/;

)..

Is there is any way to solve .it will be help full.
