7.4 FPU Exceptions

Overflow Exception (O)

The Overflow exception is signaled when the magnitude of the rounded floating-point result, with an unbounded exponent range, is larger than the largest finite number of the destination format. (This exception also sets the Inexact exception and Flag bits.)

Trap Enabled Results: The result register is not modified, and the source registers are preserved.

Trap Disabled Results: The result, when no trap occurs, is determined by the rounding mode and the sign of the intermediate result (as listed in Table 7-1).
