618ec2c84b Merge pull request #274 from BigFav/bigSin 
BigNumber Trigonometry
 2015-02-09 21:00:18 +01:00
Favian Contreras
aa4717a82d Replaced BigNumber comparisons with string comparison for the high precision acos and asin test cases, in an attempt to fix those test cases. 2015-02-09 01:56:13 -08:00
Favian Contreras
38650ba475 Slight tweeks and refactoring of the functions. Updated test cases to ensure args were not tampered with (even for functions whose precision is inherited via the number which will be changed in the future). 2015-02-09 01:33:29 -08:00
Favian Contreras
2de088cb0d Tested the functions. Made changes to the functions accordingly. Now puts more digits of pi into cosine to get the 'correct' values. 2015-02-08 18:42:18 -08:00

Big sine and cosine
 2015-02-04 14:29:58 +01:00

1b51822677 Updated tests, and slight update to the way I reduced the arguments. 2015-02-04 04:57:29 -08:00

27dc595557 Organized bignumber.js by function type. Improved speed of sin, and tried to complete cosine but that is slightly broken (gets last digit wrong sometimes). 2015-02-03 05:54:04 -08:00

05c6dcaae5 Guard digits now a function of n. Updated Infinity! to be accurate (Infinity! == sqrt(tau)). Updated and cleaned up test cases. 2015-01-14 18:15:03 -08:00
Favian Contreras
a85df3fcea Fixed precision variable problem (config.precision instead of math.precision), and round-off errors. Updated test cases. 2015-01-13 04:41:53 -08:00

188c3afdfd Fixed carry-over precision bug in factorial. Updated test cases to account for this potential error. 2015-01-12 13:06:22 -08:00
Favian Contreras
35d92bde1d Cleaned up test cases by removing string comparisons on NaN and 0 equality for bignumbers. Also, now ensuring that sin returns with correct precision. 2015-01-12 13:04:03 -08:00
Favian Contreras
676e69409b Fixed bug of not reducing into pi range when negative, and using less guard digits. Now more thorough tests. 2015-01-04 10:25:03 -08:00

05d8f5b5f6 Failed at adding gamma to the parser (attempted to add 1 to all the values while using gamma, then tried to wierdly overload ! token). I added BigNumber integer support for gamma to allow more flexibility when integrating it into the parser (if that is something that is done). 2014-12-17 16:07:26 -08:00

f36fbb3968 Added bitwise functions into the bignumber section of mathjs. Made more test cases as well. Shifts are not fully precise, but other bitwise opts are. 2014-12-15 01:02:41 -08:00

e51bb94d56 Fix the test case so it passes on all hardware. 
The fix is to test that the imaginary part is nonzero,
not that it is exactly 1e-100.
In some software / hardware combos,
it seems to return 1.0000000000000001e-100.
