Might be a little late but here's my method
# round only works on integers so have to
# multiply the float to by 10000 to round it to 2 decimal places
# and then correct the position of the decimal by
# dividing by 100.0
def round(float, num_of_decimal_places)
exponent = num_of_decimal_places + 2
@float = float*(10**exponent)
@float = @float.round
@float = @float / (10.0**exponent)
end
