Does functional programming replace GoF design patterns?
...they exist. Functional languages have plenty of best practice rules of the form "when you encounter problem X, use code that looks like Y", which is basically what a design pattern is.
However, it's correct that most OOP-specific design patterns are pretty much irrelevant in functional languages.

Fixed point vs Floating point number
...the same number of bits for each portion. For example, if your fixed point format was in decimal IIIII.FFFFF then the largest number you could represent would be 99999.99999 and the smallest non-zero number would be 00000.00001. Every bit of code that processes such numbers has to have built-in know...

John Carmack's Unusual Fast Inverse Square Root (Quake III)
...s, can be represented by a polynomial sum:
y = f(x)

y = a0 + a1*x + a2*(x^2) + a3*(x^3) + a4*(x^4) + ...
Where a0, a1, a2,... are constants. The problem is that for many functions, like square root, for exact value this sum has infinite number of members, it do...
Difference between Observer, Pub/Sub, and Data Binding
...ers. In .NET, one can use the standard events for this, since events are a form of MulticastDelegate, and so can support delivery of events to multiple subscribers, and also support unsubscription.
