Examples

Section titled “Examples”
Example 1
default
{
    state_entry()
    {
        llSay(0,"The (Float)absolute value of -4.5 is: "+(string)llFabs(-4.5) );

// The (Float)absolute value of -4.5 is: 4.500000

Notes

Section titled “Notes”
  • Using val-2*val*(val<0) is roughly 60% faster than llFabs as it avoids a function call, though it produces NaN if given an infinite value and (correctly) returns 0.0 instead of -0.0 when taking the absolute value of negative zero.

Known issues

Section titled “Known issues”

From the issue templates included by the wiki article:

  • SCR-439 (bug): Mono only: llFabs of Negative Zero is negative, should be positive.
