* 49611 based on 49590 (Martijn Dekker): disable Inf and NaN in math ↵Oliver Kiddle2021-11-301-1/+1
| | | | expressions for sh emulation
* github #82: Fix typosDimitris Apostolou2021-11-121-2/+2
|
* 48723: locale-safe recognition of "Inf" and "NaN" constants in mathVincent Lefevre2021-05-151-2/+6
|
* 48389: getkeystring() should not return ptr to local varJun-ichi Takimoto2021-04-061-1/+6
| | | | | Now it returns NULL if called with GETKEY_SINGLE_CHAR and next character is not found. Caller must check the return value.
* 46079: Ignore double quotes in math expressions.Peter Stephenson2020-06-231-0/+2
| | | | | | | Treat as white space. This is required for compatibility and previously had no use in zsh as it generated an error.
* 45343: Queue signals around arithmetic evaluationsDaniel Shahaf2020-01-291-4/+11
| | | | | The queueing added in execarith() in 45083 is reverted since the callee does this now.
* 43944: apply NO_UNSET consistently to arithmeitcMartijn Dekker2018-12-301-0/+2
|
* 43261: Fix unary minus with base.Peter Stephenson2018-08-081-2/+13
| | | | | Apply unary minus to a complete lexical constant rather than the first component that comes along.
* 43219 (except term{cap,info}.c): fix several memory leaksJun-ichi Takimoto2018-07-311-1/+1
|
* 42488: test cases for 42369 and address some issues in the codeOliver Kiddle2018-05-131-18/+19
|
* Nelson H. F. Beebe: 19597 (rebased 42369): return Inf, NaN etc from floating ↵Oliver Kiddle2018-05-131-4/+46
| | | | point operations instead of errors to allow non-stop IEEE 754 arithmetic
* 41641: Some math operations shouldn't be lvalues.Peter Stephenson2017-09-051-8/+2
| | | | | This includes pre- and post- increment and decrement. Simply mark all values after operations as rvalues.
* 40760: Always tokenize unquoted - to Dash.Peter Stephenson2017-03-071-3/+4
| | | | | | This fixes use of pattern match character ranges in unusual contexts. Attempt to detect a tokenized - in cases where we don't care.
* 40622 with typos fixed: functions -Ms.Peter Stephenson2017-03-011-10/+22
| | | | | | This adds the capability for mathematical functions based on shell functions to have a string argument. Module functions have had this for a long time.
* 37018: Make WARNCREATEGLOBAL more consistent.Peter Stephenson2015-10-291-26/+0
| | | | | Wd don't need separate math handling any more, and can make it output the function name in all cases.
* unposted: strdup should be ztrdupBarton E. Schaefer2015-10-211-1/+1
|
* 36651: WARN_CREATE_GLOBAL += math expressionsDaniel Shahaf2015-09-271-0/+25
| | | | | Without this, '() { (( x=42 )) }' and '() { for (( i=0; … )) }' wouldn't warn about $x and $i, respectively, being created global.
* 35359: Improved math parsing and errors.Peter Stephenson2015-06-021-7/+14
| | | | | | Check for bogus trailing ")" at end of top-level parse. Extend some math error messages to indicate they are math errors.
* unposted: rewrite Nularg math handling to be like other casesPeter Stephenson2015-04-151-2/+6
|
* 34892 (slightly tweaked): math evaluation fixPeter Stephenson2015-04-151-2/+2
| | | | | An empty expression resulting from substitution includes a Nularg, which needs handling the same as an empty string.
* 34280: more widespread use of FORCE_FLOAT.Peter Stephenson2015-01-151-1/+12
| | | | Add the case of variables read for use in arithmetic expressions.
* Propagate float/integer type in arithmetic assignment.Peter Stephenson2015-01-121-1/+28
| | | | | | Add test. Mention this and also floating point mod change in README.
* 34230: call fmod() for modulo with floatsBarton E. Schaefer2015-01-111-3/+5
|

|
* 31982: detection of floating point constants was problematic.Peter Stephenson2013-11-141-8/+3
| | | | | Remove the cause and fix the original problem with floating point numbers with leading zeros (users/17445) a different way.
