[new feature] auto covert possible column to numerical

[wavefancy]

change:
echo '1 2' | pawk 'int(f[0])<=1'

to:
echo '1 2' | pawk 'f[0]<=1'

We do not need to make the conversion every time, especially when we have many operations.

Thanks much!

How would this work exactly? The fields are just Python strings and the code is just normal Python.

By fastnumbers package: In [5]: from fastnumbers import fast_float, float as fnfloat In [6]: [fast_float(x) for x in ['12','bad','Na']] Out[6]: [12.0, 'bad', 'Na'] Or by try/catch except for testing: https://code-maven.com/slides/python-programming/is-number A discussion on stack overflow:https://stackoverflow.com/questions/354038/how-do-i-check-if-a-string-is-a-number-float Best regards Wallace

Sorry, I should have been clearer. I more meant how would that work at a holistic level. eg. If integer strings are converted to integers then this would fail: ','.join(f)

I don't think it's a good idea, but I'd be interested in any ideas.

','.jion(map(str,f)) would work then.

Right but then you've solved one annoyance and introduced another...
