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
