==================== Summary ====================

Ancestors: Kernel-nice.1260
Oups, I forgot to fix Float negativeInfinity < 0 when arithmetic primitives are configured to refuse to convert a SmallInteger asFloat...
=============== Diff against Kernel-nice.1260 ===============
Item was changed:
----- Method: Number>>adaptToFloat:andCompare: (in category 'converting') -----
adaptToFloat: rcvr andCompare: selector
"If I am involved in comparison with a Float, convert rcvr to a
Fraction. This way, no bit is lost and comparison is exact."
rcvr isFinite
ifFalse: [
selector == #= ifTrue: [^false].
selector == #~= ifTrue: [^true].

+ ifTrue: [^ rcvr < 0.0].
- ifTrue: [^ rcvr positive not].
(selector = #> or: [selector = #'>='])

"Try to avoid asTrueFraction because it can cost"

Item was removed:
- ----- Method: Object>>perform:with:with:with:with:with: (in category 'message handling') -----
- perform: aSymbol with: firstObject with: secondObject with: thirdObject with: fourthObject with: fifthObject
- "Send the selector, aSymbol, to the receiver with the given arguments.
- Fail if the number of arguments expected by the selector is not four.
- Primitive. Optional. See Object documentation whatIsAPrimitive."
-
