If you are using IEEE 754 math then you can try [mikeratdog mike]$ irb --simple-prompt >> negInf = *['FFF0000000000000'].pack('H*').unpack('G') => -Infinity >> inf = *['7FF0000000000000'].pack('H*').unpack('G') => Infinity >> negInf.infinite? => -1 It makes use of Complex and Rational to have no rounding errors if possible.

Ruby nil values are converted to APL Null objects Simple Ruby arrays are converted to APL arrays, with individual elements converted as above. Returns -PI/2..PI/2. Join them; it only takes a minute: Sign up Can someone explain to me NaN in Ruby? Returns a Float in the range -1.0..1.0.

For example, the method leap? It might help to think of NaN meaning "some DN> undefined value". trisweb commented Jan 6, 2013 Agreed, thanks. What does dot forward slash forward slash mean (.//)?

SUSv3 defines that lgamma(-INFINITY) is +INFINITY though tgamma(-INFINITY) is defined a domain error. Look at the graph of Log(x). a elsif a >= 0 rsqrt(a) else Complex(0,rsqrt(-a)) end end Validate Generated by RDoc 5.0.0.beta2. Why is absolute zero unattainable?

Cyclically sort lists of mixed element types? lgamma(x) is defined as log(fabs(tgamma(x))). What happens when 2 Blade Barriers intersect? NaN stands for "Not a number".

Ignore the first three irb commands. -Kurt On Tue, Aug 12, 2003 at 10:53:34AM +0900, Kurt M.

I try to write a patch for atanh, log, log2, log10, and sqrt according to the following policies: (1) Pick up domain and pole error cases before calling actual C functions. Okee dokey.

The error is raised when RubyAMF internals set the attributes hash containing NaN values for integer columns. It doesn't appear to be a constant in > > >Float or Math. > > module Math > Nan = log(-1) > end > > Now it is. > > Hal All you can do is use DN> Float.nan?
