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 |
