# Comparative

< Help(Redirected from Help/Primer/Comparative)

<=   =>

The dyad = has a result of 1 if its left and right argument are equal, and a result of 0 if they are different.

```   23 = 34
0
23 = 23
1
a =. 'd'
a = 'c'
0
7 + a = 'c'
7
7 + a = 'd'
8```

Some programming languages treat the results of comparative primitives such as = as True and False values that are not numbers. In J the results of comparatives are just numbers.

There are several other comparative verbs: less-than < , less-or-equal <: , larger-than> , and larger-or-equal >: . These comparative primitives are sometimes called relationals.

```   7 < 8
1
7 < 7
0
7 <: 7
1```
