Benchmark: If statements vs zero multiplication and assignment

If statements vs zero multiplication and assignment (version: 0)

Is it faster to check if a numeric calculation needs to be performed and assigned to an object property, or just do the calculation against zero and assign it anyway.

Script Preparation code:

var DO_MATHS_TRUE = true,
    DO_MATHS_FALSE = false,
    DELTA = 12345,
    OBJ_SRC = {x: 12},
    OBJ_SRC_ZERO = {x: 0},
    OBJ_DEST = {x: 0};

Tests:

If Statement - True
if(DO_MATHS_TRUE){ OBJ_DEST.x += (OBJ_SRC.x * DELTA) }
If Statement - False
if(DO_MATHS_FALSE){ OBJ_DEST.x += (OBJ_SRC.x * DELTA) }
Calculate - Positive
OBJ_DEST.x += (OBJ_SRC.x * DELTA)
Calculate - Zero
OBJ_DEST.x += (OBJ_SRC_ZERO.x * DELTA)
