Compile::cret1

Details

  • This message is generated when an expression to be compiled includes more than one point of return and not all of the points return an expression of the same type.
  • The return type can be _Integer, _Real, _Complex, or True|False, or arrays of _Integer, _Real, _Complex.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[Compile::cret1].

Examples

Basic Examples  (1)

One of the possible return types is an integer and the other possible return type is Boolean:

Wolfram Language code: Compile[{x}, If[x > 0, Return[1], Return[False]]]

The compilation succeeds if all of the possible return values have the same type:

Wolfram Language code: Compile[{x}, If[x > 0, Return[True], Return[False]]]
