      var value = document.getElementById('curr_basic').value;
      var elem = document.getElementById('curr_basic');
              var numexp = new RegExp('^[0-9]*\\.?[0-9]*$');
              if(value!="")
               {
              if( elem.value.match(numexp))
              {
                return true;
              }
              else
              {
               alert("Enter Numeric values only");
               elem.focus();
               return false;
              }

Are you sure? Your code works fine with 45.00. Post your HTML and the code that you call the function with.
