Returns the minimum number of x and y, favouring numbers over NaNs.
If both x and y are numbers, the minimum is returned.
If both parameters are NaN, either will be returned.
If one parameter is a NaN and the other is a number, the number is
returned (this behaviour is mandated by IEEE 754R, and is useful
for determining the range of a function).
