Subject: Really small numbers in ruby coming as zero!?

hello I have this piece of code written to analyse the cross section and
give the reinforcement for a concrete beam..

#initializing some constants.. pls ignore this part!
M = 340000000
h = 630
b = 300
fck = 40
    d = b-30

# This is where I am having my problem
    K = ((M) / (b*(d**2)*fck)).to_f

# I have defined other constants.. but didn't wanna crowd the question
    z = (d/2) * (1 + Math.sqrt(1-2*(K/kappa)))

area_steel = (M) / (fyd*z)
puts "Area of Steel Required " + area_steel.to_s + " sq. mm"

*end of code*

thanks for your help cheers!
