The TRUNC function returns a truncated number based on an (optional) number of digits. For example, TRUNC (4.9) will return 4, and TRUNC (-3.5) will return -3. The TRUNC function does no rounding, it simply truncates as specified. The TRUNC function takes two arguments: number and num_digits. Number is the numeric value to truncate. honey 4 castWebAbstractWe propose a novel, error-efficient approximate multiplier (EEAM), which is based on a rounding-based approach (RBA).
