if statements

[cwl157]

How do you say less than or equal to in an if statement. I know:
if(x==0) says if x equals zero but how do you write x is equal to or less than zero.

thanks

Thanks and does that mean that greater than or equal to is >= or is it => ?

[Garadon]

it is always the 1st sign that alters

== equal
<= less or equal
>= larger or equal
!= not equal.
