The SGN function returns the sign of a number value.

Syntax: sign% = SGN(value)

  • Returns -1 when a sign is negative.
  • Returns 0 when a value is zero.
  • Returns 1 when a value is positive.
  • Used to hold the original sign of a number.

Example: Checking and changing negative values to positive ones.

n = -100
IF SGN(n) = -1 THEN n = ABS(n)

Screen result: 100
