Trigonometric functions in UDF

er.mkumar · September 24, 2012, 08:48

Hello,

Is it that while using trigonometric functions like tan(arg) we should ensure 'arg' in degrees or radians too work.

kindly clarify as my UDF is not running (showing floating point error: invalid no) when I use 'arg' in radians while its not giving proper result while using 'arg' as degree.

Regards,
mukesh

Issue Resolved!

As we all know in 'C language' argument of Trigonometric functions shall be in radians, similarly while writing UDF the argument(if in DEGREE) must be multiplied by (M_PI/180) else not required if argument is in RADIANs.
