for this reason, the float is persisted until the resulting mantissa is sufficient to fill the Mantissa field, after which the extra bits are rounded. In other words, the decimal-to-binary transformation is not guaranteed to be accurate, but only approximate, in addition to the accuracy issues previously mentioned. In fact, only a very small number of decimal decimals have accurate binary floating-point representation. Coupled with the accumulation of errors in floating-point arithmetic, the re
