SIGN

The SIGN function transfers the sign of a2 to the magnitude of a1.

Format

SIGN (a1,a2)

Definition

SIGN(a1,a2) =  ABS(a1) if a2 > 0
SIGN(a1,a2) = -ABS(a1) if a2 < 0

Arguments

a1: Any valid function expression or constant.
a2: Any valid function expression or constant.

Example

VARIABLE/23, FUNCTION=10*SIGN(DM(24,33),VZ(24,33))
When VZ(24,33)>0, the value of VARIABLE/23 is +10*DM(24,33). 
When VZ(24,33)<0, the value of VARIABLE/23 is -10*DM(24,33).

Comments

The SIGN function is discontinuous. Use this function with care to avoid creating expressions that are discontinuous.
