| Summary | 0006983: Float nan isLiteral. It should not. | ||||||||
| Description |
There is no way to store Float nan as a literal. (Yes there is one, but there should not. It is a bug of Number>>readFrom:, see 0006982) Examples: self assert: (Compiler evaluate: Float nan storeString) isNan. self assert: (Compiler evaluate: (Array with: Float nan) storeString) first isNan. |
||||||||
| Additional Information |
I have an easy and cheap way to define isLiteral which is synonym of isFinite: ^(self - self) isZero |

Note that there are still literal representation of Float infinity, like 1.0e1000. However, since Float infinity is not able to print literaly, and isLiteral is intended for print, i think it's better to answer false for infinite Floats too. Unless you really like (Array with: Float infinity) to be printed #(1.0e1000) ? |

Note that the patch does not solve storeString bugs indicated above. See 0001631 for a possible solution. (Array with: Float nan) storeString -> '((Array new: 1) at: 1 put: NaN; yourself)' A side effect is that Float nan and Float infinity are no more selfEvaluating... (which is true until 0001631 is fixed). |
