Help with data type

[madhankrish]

Hello all,
I am supposed to multiply 10 float values. (like 0.002, 0.004, 0.006, etc...)
Which data type will best suit the product of these float values?
I used 'long double' but I am still getting 0 as the product.
(I have initialised the product as 1. So, no problem with that.)
Can someone suggest a suitable data type which can handle longer decimal places. Also pls mention the representation to be used ie.%f or something like that.
Thanks

float should be OK -the product is probably getting too small to print using %f, try %g which will give number with an exponent such as 1.2e-008, e.g.

       printf("product %g\n", product);
