Hi, all
i have a code that uses _fpclass function,this code is working fine on windows but it fails to work under linux and it reports the following error when i compile with linux (gcc)..
â_fpclassâ was not declared in this scope

is there any alternate function to be used on linux ?and i need to work this code on both windows as well as linux
please guide me in resolving this issue.
