The SIGN(a1,a2) function transfers the sign of the value of the expression a2 to the magnitude of the expression a1.
SIGN(a1,a2) = ABS(a1) if a2 ≥ 0
SIGN(a1,a2) = -ABS(a1) if a2 < 0
Arguments
a1 |
Any valid function expression. |
a2 |
Any valid function expression. |
Cautions
The SIGN function is discontinuous. Use this function with care when defining expressions for motion or forces.
