Hi Guys,

can anyone tell me how I can convert a char-Array to a float or an int?
Kind Regards,

 Thank you very much!



Okay, i figured it out how to do the conversion from char[] into a 
float. I searched now for about 2 hours how to make this in the other 
direction: float -> char[]
Or any other buildin type (int, flaot, double, etc.), but I couldn't 
find any useful information about this in the documention.

Is there any good documention outside there how to convert between 
different types including char[]? Or generally a tutorial or 
documentation about handling char[] and conversion?

Please see to std.string module:
char[] toString(bool b);
char[] toString(char c);
char[] toString(ubyte ub);
char[] toString(ushort us);
char[] toString(uint u);
char[] toString(ulong u);
char[] toString(byte b);
char[] toString(short s);
char[] toString(int i);
char[] toString(long i);
char[] toString(float f);
char[] toString(double d);
char[] toString(real r);
char[] toString(ifloat f);
char[] toString(idouble d);
char[] toString(ireal r);
char[] toString(cfloat f);
char[] toString(cdouble d);
char[] toString(creal r);
	 Convert to char[].

Documentation for Phobos is far from perfect, but you can find most 
necessary things anyway.

A "see std.string for convertions in the other way" would be nice in the 
documentation (same for std.conv in the other way).

Personally I think having them in seperate modules is a mistake. both
toFloat(char[]) and toString(float) should be in std.conv IMHO!

Or just place a public import of std.string in std.conv.  That would do the
trick without 
either module getting too massive.
