1. A method for video coding, comprising:
receiving, by a decoder, an extended precision processing flag that indicates whether an extended dynamic range is used for transform coefficients in transform processes based on a value of the extended precision processing flag;
receiving, by the decoder, an extended precision processing constraint flag in general constraint information syntax to provide general constraint controls for the extended precision processing flag; and
in response to determining that the value of the extended precision processing constraint flag equals to 1, determining that the value of the extended precision processing flag shall be equal to 0.
