#3232 closed Bug (Fixed)

Issue when parsing scientific notation literals

Reported by: jchd18 Owned by: Jon

Version: Severity: None

Description (last modified by jchd18)

The runtime parser sometimes fails on reals in scientific notation immediately followed by some operators or silently gives a wrong result in some cases.

$x = 1e2 + 10
ConsoleWrite($x & @CRLF)	; 110 OK
$x = (1e2)+10
ConsoleWrite($x & @CRLF)	; 110 OK

$x = 1e2+10
ConsoleWrite($x & @CRLF)	; 100 Wrong!
$x = 1e2-10
ConsoleWrite($x & @CRLF)	; 100 Wrong!
$x = 1e2^10
ConsoleWrite($x & @CRLF)	; 1e+020 Wrong!
$x = 1e2+ 10			; Unable to parse line.
ConsoleWrite($x & @CRLF)
$x = 1e2- 10			; Unable to parse line.
ConsoleWrite($x & @CRLF)
$x = 1e2^ 10			; 1e+020 Wrong!
ConsoleWrite($x & @CRLF)

+, - and ̂ are the only arithmetic operators affected: * and / seem to work correctly. (It was fun composing the exponentiation sign here!)

If I run Tidy on those lines, I get the correct results.

comment:2 Changed 8 years ago by jchd18

That's obvious, since tidying the code inserts whitespace between literals and operators, when needed, for readability. The bug remains that untidied code isn't parsed correctly or gives wrong results.
