Subject: Re: How do I round off a float to x decimal places


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
