* New <math.h> macro named issignaling to check for a signaling NaN (sNaN).Thomas Schwinge2013-04-028-15/+177
| | | | It is based on draft TS 18661 and currently enabled as a GNU extension.
* Fix casinh inaccuracy for imaginary part < 1.0, real part small (bug 10357).Joseph Myers2013-03-304-0/+1133
|
* Fix casinh inaccuracy near i, imaginary part > 1 (bug 15307).Joseph Myers2013-03-274-0/+491
|
* BZ#13889: expl (709.75) wrongly overflows for ldbl-128ibmAdhemerval Zanella2013-03-221-0/+3
| | | | | | The patch increase the high value to check if expl overflows. Current high mark value is not really correct, the algorithm accepts high values. It also adds a correct wrapper function to check for overflow and underflow.
* libm-test: Properly wrap blocks consisting of several statements.Thomas Schwinge2013-03-211-8/+14
|
* On 32-bit x86, disable certain tests involving sNaN values.Thomas Schwinge2013-03-211-10/+22
| | | | Follow-up to commit 495ded2c8c1eb8c0ac4b54add2dd397852e19cba.
