In a computer system, the signed numbers cannot be represented by

In computer architecture, signed numbers (integers) are typically represented using three standard methods:

• Signed Magnitude: The most significant bit (MSB) acts as the sign bit (0 for positive, 1 for negative), while the remaining bits represent the magnitude.
• One's Complement: Negative numbers are represented by inverting all bits of the corresponding positive binary number.
• Two's Complement: This is the most common representation in modern systems. It is obtained by adding 1 to the one's complement of the number. It allows for efficient arithmetic and provides a unique representation for zero.

Float magnitude is not a recognized or standard scheme for representing signed numbers in a computer system. While floating-point numbers (e.g., IEEE 754) represent signed real numbers using a sign bit, exponent, and mantissa, the specific term "float magnitude" is not a valid representation method for signed integers.
