Arguments
| condition : | Bool (pass by const reference) |

Details
The ifelse function is important when the value of a variable should deterministically change during an analysis depending on other variables. Standard if-else statements are not dynamically re-evaluated.
Example
a <- 1
b := ifelse( a == 1, 10, -10 )
b
a <- 2
b
