- look at the sign bit in the bit pattern;
using the ISO C
copysign()
function (IEEE 754
copySign operation) to copy the sign of the zero to some non-zero...
- and x ≠ NaN for any x (including NaN).
copysign(x,y)
returns x with the sign of y, so abs(x)
equals copysign(x,1.0). This is one of the few operations...
- sqrt(1 + t * t); s = -1 / u; c = t / u; r = b * u; end end The IEEE 754
copysign(x,y) function,
provides a safe and
cheap way to copy the sign of y to x...
