19 mar 2012 · int abs(int v) {. return v * ((v>0) - (v<0)); } This code multiplies the value of v with -1 or 1 to get abs (v). Hence, inside the parenthesis will be one of -1 or 1. If v is positive, the expression (v>0) is true and will have the value 1 while (v<0) is false (with a value 0 for false).
20 mar 2009 · On most CPUs and all compilers x = (x>=0)? x:-x; is fastest way to get absolute value, but in fact, often standard functions already offer this solution (e.g. fabs()). It is compiled into compare followed by conditional assignment instruction(CMOV), not into conditional jump.
The abs() function in C++ returns the absolute value of the argument. It is defined in the cmath header file. Mathematically, abs(num) = |num|.
