# value is not null

X != null

• value

## Outputs

• value is not null? (0/1)

## Neuron type

Best algorithm has been found - locked

## Patterns

Pattern Input Output
1.
 value: null
 value is not null? (0/1): 0
2.
 value: abc
 value is not null? (0/1): 1
3.
 value: 3
 value is not null? (0/1): 1
4.
 value: -90
 value is not null? (0/1): 1

## Applicable neurons

• IF
• a > b
• a = b
• a is not b
• IF a=b THEN c ELSE d
• IF (1) THEN a ELSE b
• null
• sql A+B
• IfNull
• select sum (A, B, C)
• value is null
• Simple interest
• Connect - four inputs
• character a
• word city
• Chemical element - atomic number
• Half of number
• convert HH:MM:SS into seconds
