[PHP-DEV] Patch for ext/standard/[basic_functions.c|php_math.h|math.c] From: Jesus M. Castagnetto (jmcastagnetto <email protected>)
Date: 07/31/01

I am sending this patch to the php-dev list for your
consideration. Attached are the listing produced with
"cvs diff -u", and listed below is a test file to
check the changes.

Basically I just added some more math funcs from the C
library (hyperbolics and exponentials).

The files changed are:

ext/standard/basic_functions.c
ext/standard/php_math.h
ext/standard/math.c

And the added test file is:
[ext/standard/tests/math/002.phpt]
--TEST--
Test of trigonometric and exponential functions

<?php
  function pfloat($func, $params) {
          $fmt = "%.6f\n";
          $fcall = (is_array($params)) ?
"call_user_func_array" : "call_user_func";
          printf($fmt, $fcall($func, $params));
  }
  pfloat("sin", -1);
  pfloat("cos", -1.5);
  pfloat("tan", -1);
  pfloat("asin", 0.4);
  pfloat("acos", -0.5);
  pfloat("atan", 1.0);
  pfloat("atan2", array(1.5,3.0));
  pfloat("sinh", -1);
  pfloat("cosh", -1.5);
  pfloat("tanh", -1);
  pfloat("asinh", -1.5);
  pfloat("acosh", 1.1);
  pfloat("atanh", 0.1);
  pfloat("exp", 1.5);
  pfloat("exp2", 1.5);
  pfloat("exp10", 1.5);
  pfloat("expm1", 1.5);
  pfloat("log", 1.1);
  pfloat("log2", 2.3);
  pfloat("log10", 1.2);
  pfloat("log1p", 10.0);
