Hello everyone,

 

Although i have used  #include <math.h>, cc compiler

reports 'redundant redeclaration' and 'undefined

reference to round'.

 

Which header file should be included to using math function?

 

 

It's not a question of gnome, but i have no other mailist.Sorry 

Hi,
Read 'man round'. It says that round() conforms to C99, so you have to pass '-std=c99' as an option to gcc.
