_controlfp in C#?

[Logan McKinley]

I was told by a vendor that somehow floating point exceptions become enabled
after calling their Dll and I should call _controlfp to solve the "Overflow
or underflow in the arithmetic operation." error I am getting in my C#
application. I am having trouble finding information about _controlfp with
regards to how it effects and or how it is used in .Net.
Any Information would be appreciated

[DllImport("msvcrt.dll")] private static extern int _controlfp(int IN_New,
int IN_Mask); // this imports the call
private const int _MCW_EM = 0x0008001f;
private const int _EM_INVALID = 0x00000010;


_controlfp(_MCW_EM, _EM_INVALID); // this is the call
