Script Preparation code:

var abs = Math.abs
var x = -0.00034254146579137945;
var cycle_counter = 10000000;

Tests:

Math.abs
for(i=0; i<cycle_counter; i++){ var result = Math.abs(x); }
abs
for(i=0; i<cycle_counter; i++){ var result = abs(x); }
Custom1
for(i=0; i<cycle_counter; i++){ var negative = x < 0.0 ? 1 : 0; var result = x - x * 2.0 * negative; }
Custom2
for(i=0; i<cycle_counter; i++){ var result = x & -1; }
Compare
for(i=0; i<cycle_counter; i++){ var result = x < 0 ? -x : x }
Bitshift
for(i=0; i<cycle_counter; i++){ var result = (x ^ (x >> 31)) - (x >> 31) }
