ckfinite

throw ArithmeticException if value is not a finite number.

The stack transitional behavior, in sequential order, is:

  1. value is pushed onto the stack..

  2. value is popped from the stack and the ckfinite instruction is performed on it.

  3. value is pushed back onto the stack if no exception is thrown.

The ckfinite instruction throws ArithmeticException if value (a floating-point number) is either a "not a number" value (NaN) or a +- infinity value. Ckfinite leaves the value on the stack if no exception is thrown. Execution is unspecified if value is not a floating-point number.

ArithmeticException is thrown if value is not a 'normal' number.

Note that a special exception or a derived class of ArithmeticException may be more appropriate, passing the incorrect value to the exception handler.

The following Emit method overload can use the ckfinite opcode:

  • ILGenerator.Emit(OpCode)
