Hello J world, I have a verb that returns scalar 1 if the argument is numeric of any shape and scalar 0 otherwise. It works fine:
numeric i. 5
1
numeric 9
1
numeric i. 2 3 4
1
numeric 'cat'
0
numeric 3#<i. 4
0
My definition feels clumsy, however. Can anyone suggest something nicer?
numeric=: monad : '0 -: 0{ , 1{. 0#y'
