= returns 1b if two variables are equal, and 0b if they are not. Unlike match, it operates on atoms:

q)"hello" = "world"
00010b

Also unlike match, = is not strict with regard to type:

q)1~1h
0b
q)1=1h
1b

= uses comparison tolerance when matching floats:

q)(1 + 1e-13) = 1
1b

For more information, see Q for Mortals.
