Hi all, Is there some way in numarray to find out what the maximum and minimum values are that a type can hold? For instance, is there a convenient way to find out what the maximal possible value of the Float32 type is? Cheers, Peter -- Dr. Peter J.

I think the answer is "no". I added a feature request on Source Forge.

Nope.

I am not completely sure what is behind of the following way but
numarray.fromstring('\xff\xff\x7f\x7f','f') array([ 3.40282347e+38], type=Float32)
seems to give the maximum value for Float32. Pearu

Sure, it is not too difficult to find the minimum and maximum values of each type, given the bitsize (although there may be portability issues). But it would be convenient to have such properties directly accessible in numarray, I think. Peter
