Calculates the square root of the given argument.

What is ipow function in ABAP?

Calculates the base raised to the power of an exponent, e.g., result = ipow(base = 2 exp = 3) computes 8.

What is operator precedence in arithmetic expressions?

The order of operations, including parentheses, multiplication, division, modulo, addition, and subtraction.

What happens when dividing 2 / 3 in ABAP with different result types?

If TYPE i, result is 0; if TYPE p LENGTH 8 DECIMALS 0, result is 1; if TYPE p LENGTH 8 DECIMALS 2, result is 0.67.

What does the TYPES t_result TYPE p LENGTH 8 DECIMALS 2 declaration do?
