std.math.exp() should be @trusted because it can fall back to core.stdc.math.exp().

e312f9898b Strict @property syntax compliance. 
This enables the test suite to build with the -property switch enabled.

std.cpuid: vendor()/processor() have not been converted to properties in accordance to core.cpuid.
std.xml: Element.text() cannot be a property due to the optional parameter.

32dadd0286 std.math: Fix modf() documentation, add fmod() 
The documentation for std.math.modf() actually describes the fmod()
function of C's math.h, which doesn't have a counterpart in std.math.
This commit adds fmod() and fixes the documentation for modf().

This fixes issue 4765.

69e8663fc1 Add sin(), cos() and sqrt() to std.complex 
This also requires std.math.coshisinh() to be accessible to std.complex,
so I changed its protection attribute to "package".

ea8e37d350 denormalizedException -> subnormalException 
The term "denormal" is deprecated by IEEE, and should be replaced by
"subnormal" in all cases. Fix all the comments to make sure this confusion
doesn't happen again.

e3c1185692 IEEE exceptions and status flags are properties 
They are all global properties of the processor, so it makes a lot of sense
for them to look like global variables.

77aa890a72 Add denormalizedException 
The denormalizedException is set whenever a denormalized value is
manipulated or created. It is useful to know that denormalized values
are generated because it indicates that precision is low.
Further performance of denormalized number can be up to 100 times slower
even when handled in hardware (see Table 2 in "Quantifying the
Interference Caused by Subnormal Floating-Point Values" by Isaac Dooley
and Laxmikant Kale).

9fec44b8f9 Remove the "NotImplemented" exception, and turn it into a simple assert. This allows all functions to be marked as nothrow. I have marked them all as @safe/@trusted as well. 2010-11-12 08:00:53 +00:00

b6890792bf D implementation of pow(), avoiding dependence on C. The big benefit is that pow() is now pure, but also improved accuracy of corner cases. 
All math functions are now @safe or @trusted, and all are pure nothrow except where implemented by C functions.
