abs()

which is faster, /prog/?

const int SIZE_OF_DOUBLE = sizeof(double) * 8;

double absoluteValue = (double)(bitset<SIZE_OF_DOUBLE>((unsigned long)value).set(SIZE_OF_DOUBLE - 1, 0).to_ulong());

VS.

double absoluteValue = abs(value);

OR

is there an easier way to unset a double-precision value's sign bit?

char * c; 

asprintf(&c, "%+g", value);

*c = 43;

sscanf(c, "%lf", &absoluteValue);
