- Sjoerd van Leent (4/28) Oct 09 2004 BTW, std.math also includes the sqrt() function.
- Tyro (4/35) Oct 09 2004 However, there are conflicting defininitions of sqrt() in std.math.
- Asaf Karagila (9/44) Oct 09 2004 i kind of solved my problem before i saw the replies, i used the std.mat...
- Tyro (3/26) Oct 09 2004 There is no sqrt() function in the std.intrinsic module. The

Hi, i'm pretty new to D, i was never too much a C/C++ programmer, so i don't have too much knowledge from that side, i've got one simple question, how do i use a sqrt() function in D ? at first, i figured, if its in math.h, i would use 'import std.c.math' and just call out sqrt(), but it didn't work. seeing how i don't have anyone using D that i know, i came here.. thanks in advance, Asaf.

This module has the sqrt() function build in. Before going any further, it may be wise to read the Phobos page at the place a little bit. http://www.digitalmars.com/d/phobos.html Regards, Sjoerd
