Final answer:
To declare a numerical variable precise and initialize it to the value 1.09388641, you can use the code 'double precise = 1.09388641' in a programming language.
Step-by-step explanation:
To declare a numerical variable precise and initialize it to the value 1.09388641, you can use the following code in a programming language:
double precise = 1.09388641;
This code declares a variable called 'precise' of type double and assigns it the value 1.09388641. The 'double' data type is used for storing decimal numbers with a higher precision than the 'float' data type.
