The error message indicates that the types of the input (long integer) and bias (floating point) must match.

edit

This means that the program is expecting the input to be a long integer, but the value of the bias is a floating point number. The data types of the input and the bias must be consistent in order for the program to perform the desired operation correctly. To resolve the issue, you can either convert the input to a floating point number or convert the bias to a long integer, depending on the requirements of your program.
