ds_set_precision(prec);
| Argument | Description |
|---|---|
| prec | The precision value (default 0.0000001) |
Returns: N/A
When comparing values, for example when searching in a map or
sorting a list, GameMaker: Studio must decide when two
values are equal. For strings and integer values this is clear but
for real numbers, due to floating point round-off errors, seemingly
equal numbers can easily become unequal. For example, it's possible
that (5 / 3) * 3 will not be equal to 5! To help
avoid this, a precision value is used on all real number functions,
and when the difference between two numbers is smaller than
this precision they are considered equal. The default a precision
of 0.0000001 is used for all data structure functions unless
changed by this function.
NOTE: This precision is used in all data structures but
not in other comparisons in GML!
ds_set_precision(0.0001);
The above code will change the default precision setting for all data structure functions.
