fnorm
Operation (like fma) Font Conventions
Instruction Type F
Format
(qp) fnorm.pc.sf f1 = f3 pseudo-op of: (qp) fma.pc.sf f1 = f3, f1,f0
Description
f3 is normalized and rounded to the precision indicated by pc (and possibly FPSR.sf.pc and FPSR.sf.wre) using the rounding mode specified by FPSR.sf.rc, and stored in FR f1.
If FR f3 is a NaTVal, a NaTVal is stored in FR f1 instead of the computed result.
For the encodings and interpretation of the status field's pc, wre, and rc, see Floating-point Computation Control Definitions and Floating-point Rounding Control Definitions.
