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);
