Andrew Kelley	be16034275	std.math: remove constants that can be derived ... from others at compile time	2017-08-20 05:43:40 -04:00
Andrew Kelley	987768778a	bit shifting safety ... * add u3, u4, u5, u6, u7 and i3, i4, i5, i6, i7 * shift operations shift amount parameter type is integer with log2 bit width of other param - This enforces not violating undefined behavior on shift amount >= bit width with the type system * clean up math.log, math.ln, math.log2, math.log10 closes #403	2017-08-19 01:43:43 -04:00
Andrew Kelley	2234788fa8	add ability to explicitly cast float to integer ... closes #414	2017-08-07 15:57:41 -04:00
Marc Tiehuis	5bbec42a4e	Add math special case tests and general fixes ... - Should cover special case inputs for most functions - Fixed a number of runtime panicking behaviour reliant on shift overflow/division by zero etc.	2017-06-20 23:10:22 +12:00
Andrew Kelley	c9fc8bd802	workaround for llvm bug ... See #393 for details	2017-06-19 14:36:33 -04:00
Marc Tiehuis	4c16f9a3c3	Add math library ... This covers the majority of the functions as covered by the C99 specification for a math library. Code is adapted primarily from musl libc, with the pow and standard trigonometric functions adapted from the Go stdlib. Changes: - Remove assert expose in index and import as needed. - Add float log function and merge with existing base 2 integer implementation. See https://github.com/tiehuis/zig-fmath. See #374.	2017-06-16 20:32:31 +12:00
Andrew Kelley	7f0620a20f	partial implementation of printing floating point numbers with errol3 ... also add bitCast builtin function. closes #387	2017-06-14 00:24:25 -04:00
