[Numpy-discussion] NaN value processing in weave.inline code

[Joon Ro]

Hi,

I was wondering if it is possible to process (in if statement - check if the given value is NaN) numpy NaN value inside the weave.inline c code.

testcode = '''

if (test(0)) {
      return_val = test(0);
}
'''

err = weave.inline(testcode,
 ['test'],
type_converters = converters.blitz, force = 0, verbose = 1)

with test(0) = nan returns err = nan correctly, but I don't know how to check the nan value inside the c inline c code. Is there any way I can get similar functionality as isnan?

Thank you,

Joon
