Why all the explanations on LSTM gates mention 0 and 1 output, whereas sigmoid and tanh can have continuous values in [0,1] and [-1,1] respectively?

I see all the explanations which say that '0' output in forget gate leads to stopping of particular value in past state, whereas '1' allows it. But the sigmoid function is continuous in the range...

While using Gaussian window for signal truncation, the term 'sqrt(pi)/a' is omitted and simply e^(−π^2t^2 /a^2) is used. Why so?

I have seen such expression in many research publications. Why is the preceding term neglected?
