if('condition','true','false') - Returns 'true'-statement if logical 'condition'-statement is true (non-zero), 'false'-statement otherwise.
Advice: Choose it from the Programming palette
The "if" programming tool returns a value depending on Boolean 'condition'. Boolean condition can be formed by using Boolean palette. Here is a simple example, returning numeric or symbolic result.
The user should take care when defining a function which uses "if". The Boolean condition could be sometimes quite "tricky". For example, if we want to find out if the y-value is inside (x,z) range we could do something like this.
It is advisable to see the tooltip and the order (precedence) of operators. The operators are usually calculated from left to right. Use ( ) - parenthesis if you have some doubts.
