專利摘要(中)
一種浮點數運算方法，應用於第一浮點數與第二浮點數的乘法運算。第一浮點數包含第一符號、第一指數及第一尾數，第二浮點數包含第二符號、第二指數及第二尾數。方法包含使用算術單元進行以下步驟：將第一指數與指數閾值比較，其中當第一指數不小於指數閾值，將第一尾數與第二尾數相乘以產生一尾數運算結果；根據尾數運算結果、第一指數與第二指數的指數運算結果產生計算後浮點數。

專利摘要(英)
A floating-point number operation method applied to multiplication operation of a first floating-point number and a second floating-point number is provided. The first floating point number includes a first symbol, a first exponent and a first mantissa. The second floating point number includes a second symbol, a second exponent and a second mantissa. The method includes using an arithmetic unit to perform: comparing the first exponent to an exponent threshold, wherein when the first exponent is not less than the exponent threshold, generating a mantissa operation result by multiplying the first mantissa and the second mantissa when the first exponent is not less than the exponent threshold value; and generating a calculated floating point number according to the mantissa operation result and an exponent operation result of the first exponent and the second exponent.
