float fneg (float x); |
Floating point negation.
fneg returns negated value of floating point argument x.
This routine performs the same operation as the C '-'
unary minus operator applied
to a floating point operand, but it is kept here for backwards compatibility.
At the fundamental level, fneg is exactly the same routine as
bcdneg.
