T-SQL Round Up function Revisited

In October Last year I posted a function to round up a number. I have had to adapt that function to cater for varied decimal places. Please email me any suggestions or alterations.

CREATE FUNCTION [dbo].[udfRoundUp]
(
@Num1 FLOAT,
@NumberOfDecimalPlaces INT = 0
)
RETURNS FLOAT
AS
BEGIN
DECLARE @Temp FLOAT
SET @Temp = 0

IF @Num1 - CAST(ROUND(@Num1, @NumberOfDecimalPlaces) AS FLOAT) > 0
BEGIN
/* When rounding we cannot just add 1 */
/* Calculate the round up value */
SET @Temp = POWER(10, (@NumberOfDecimalPlaces * -1))

END

RETURN ROUND(@Num1, @NumberOfDecimalPlaces) + @Temp

END
