* Incompatible Lisp Changes in Emacs 28.1
---
** Some floating point numbers are now handled differently by the Lisp reader.
In previous versions of Emacs, floating point numbers like 1.e6 would
be read as 1. This has now been changed, and the Lisp reader will now
read that construct as 1000000.0.
That is, (read-from-string "1.e6") => (1000000.0 . 4) now.
** Some floating-point numbers are now handled differently by the Lisp reader.
In previous versions of Emacs, numbers with a trailing dot and an exponent
were read as integers and the exponent ignored: 2.e6 was interpreted as the
integer 2. Such numerals are now read as floats with the exponent included:
2.e6 is now read as the floating-point value 2000000.0.
That is, (read-from-string "1.e3") => (1000.0 . 4) now.
