The SGN function returns the sign of a number value.


Syntax

sign% = SGN(value)


  • Returns -1 when a sign is negative, 0 when a value is zero, or 1 when a value is positive.
  • Function is used to store the original sign of a number.
  • QB64 allows programs to return only _UNSIGNED variable values using a _DEFINE statement.


Example: Checking and changing negative values to positive ones.

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