使用大和小浮点值二者来执行算术运算
摘要：
提供用于在数据处理系统中执行浮点算术运算的机制。接收浮点算术运算的多个浮点操作数，并且对多个浮点操作数中的至少一个浮点操作数的尾数中的位进行移位。尾数中被移位到至少一个浮点操作数的尾数的位范围以外的一个或者多个位被存储，并且基于所存储的、该尾数中被移位到至少一个浮点操作数的尾数的位范围以外的一个或者多个位生成矢量值。基于矢量值和多个浮点操作数生成用于浮点算术运算的结果值。
摘要（英）：

Mechanisms are provided for performing a floating point arithmetic operation in a data processing system. A plurality of floating point operands of the floating point arithmetic operation are received and bits in a mantissa of at least one floating point operand of the plurality of floating point operands are shifted. One or more bits of the mantissa that are shifted outside a range of bits of the mantissa of at least one floating point operand are stored and a vector value is generated based on the stored one or more bits of the mantissa that are shifted outside of the range of bits of the mantissa of the at least one floating point operand. A resultant value is generated for the floating point arithmetic operation based on the vector value and the plurality of floating point operands.
