SerializeHexReal (FUN) ¶ FUNCTION SerializeHexReal : STRING(32) Converts a floating point number to the format R16#{Mantissa}H{Exponent} where both mantissa and exponent are hexadecimal numerals, such that liM * 2^iE = {Mantissa} * 16^{Exponent}. Note If uE is zero, {Exponent} is set to 0, regardless of the value of uE. The hexadecimal exponent is computed as floor(iE/4). The hexadecimal mantissa then becomes liM * 2^(iE mod 4). See also DeSerializeHexReal. InOut: Scope Name Type Comment Return SerializeHexReal STRING(32) Input liM LINT The (signed) mantissa iE INT The (unbiased) exponent
