Description

Computes the absolute value of a 128-bit quad-precision floating-point number in VSR vB by clearing the sign bit and stores the result in VSR vD. This VSX instruction does not modify FPSCR exception flags or condition registers.

Operation

vD ← vB with sign bit cleared

Programming Note

When Rc=1, CR1 is set from the FPSCR[FX, FEX, VX, OX] bits immediately after the operation completes.
