Fabian Homborg	634feac600	[docs] Remove mention of cached variables from math ... The variable cache was removed in 95162ef19d, so this is now wrong.	2018-02-04 23:26:21 +01:00
David Adam	91a0ba9be5	Revert part of "Revert "Cache math expressions"" ... 56d9134534 contained an LRU cache plus changes to the documentation; 95162ef19d reverted both. This commit re-adds the documentation changes, which are still correct.	2017-09-01 21:55:50 +08:00
ridiculousfish	95162ef19d	Revert "Cache math expressions" ... This reverts commit 56d9134534. An LRU cache in the shell for math seems like overkill.	2017-09-01 00:25:40 -07:00
Kurtis Rader	56d9134534	Cache math expressions ... This implements an LRU cache of recently seen math expressions. When executing math inside loops and the like this can provide a 33% decrease in the time to execute the `math` command.	2017-08-24 12:18:39 -07:00
Kurtis Rader	b816cd6d50	Change how math rounds integer results ... We need our `math` builtin to behave like `bc` with respect to rounding floating point values to integer to avoid breaking to many existing uses. So when scale is zero round down to the nearest integer. Another change for #3157.	2017-08-23 17:31:04 -07:00
Kurtis Rader	24d251ff4b	Implement support for multiple math expressions ... The MuParser supports the concept of multiple expressions separated by commas. This implements support for that so that you can do things like this: set results (math '1+1, 4*2, 9^2')	2017-08-23 17:14:54 -07:00
Kurtis Rader	41a7b9457c	Implement bare minimum builtin math command ... This is the second baby step in resolving #3157. Implement a bare minimum builtin `math` command. This is solely to ensure that fish can be built and run in the Travis build environments. This is okay since anyone running `builtin math` today is already getting an error response. Also, more work is needed to support bare var references, multiple result values, etc.	2017-08-23 14:43:45 -07:00
Kurtis Rader	98449fec51	fix math regression ... The previous change to use `argparse` for parity with every other builtin and function introduced a regression. Invocations that start with a negative number can fail because the negative value looks like an invalid flag.	2017-07-14 16:03:31 -07:00
Kurtis Rader	d97c22df2d	add floating point output to math command ... This makes it easy for the user to request floating point output with the desired number of digits after the decimal point (not to be confused with significant digits). Note that this is just a thin wrapper so someone can say `math -s3 10 / 3` rather than `math "scale=3; 10 /3"`. Resolves #1643	2016-05-03 19:29:04 -07:00
Mark Griffiths	137abd0cfa	Make line length, wrapping and spacing consistent	2014-09-03 14:43:26 +01:00
Mark Griffiths	1052eeee8c	Simplify styling	2014-09-03 14:43:25 +01:00
Mark Griffiths	d282bc4625	Documentation update ... Rework for Doxygen >1.8. Moved large parts of the documentation to a simplified format, making use of Markdown enhancements and fixing bad long options.	2014-09-03 14:43:24 +01:00
Alan Thompson	07944cfd20	Change terminology in docs from 'environment variables' -> 'shell variables'	2014-04-29 07:27:56 +02:00
David Adam (zanchey)	1287b9d823	Help cleanup ... Large list of changes, including formatting and typos for most commands. More substantive changes have been made to alias, bind, block, break, builtin, case, cd, commandline, count, else, emit, fish_config, funced, function, functions, history, math, mimedb, nextd, not, popd, prevd, pushd, pwd, random, read, set, set_color, switch, test, trap, type, ulimit, umask, and while.	2013-05-13 01:48:20 -07:00

axel	1b71f91a01	Update documentation display code to run roff on the client system instead of pregenerating documentation and compiling it into program binaries ... darcs-hash:20061117162438-ac50b-5c4c7f0bd8bf53a16e16ecfead9569e642b7160f.gz	2006-11-18 02:24:38 +10:00
