Math Functions

 

The abs command returns the absolute value of an expression.  An absolute value is a number without regard for its sign, for example the absolute value of 8 and -8 is 8.  An absolute value can also be thought of as its distance from zero which is always a positive value.

 

One of the popular uses for the abs command is when working with axis to start combos.  Such as in fighting games where many users tend to use the right stick to start a combo.  So if you wished for the same combo ro be run if for example the right stick was pushed left or right, instead of using an or ( || ) operator or using two if commands you could just do this;

 

main {       if( abs(get_val(XB1_RX)) > 70 ) // if RX is greater than 70 or less than -70...         combo_run(my_combo);   }   combo my_combo {     //Do something }

 

 

 

 

 

 

 

inv returns the inverted value of an expression or number.  This means a positive value will be turned in to a negative value and vice versa, which is the same as multiplying the value by -1.  For example;

 

int a = 100; int b = -50;   main {       a = inv(a);  // a = -100         b = inv(b);  // b = 50   }

 

One of the popular uses for this command is to invert the right sticks Y axis.  For example, if you prefere to play with an inverted aim but come across a game which doesn't support it, with one line of code you can have the CronusMAX PLUS invert the axis for you.   Like so;

 

main {       set_val(XB1_RY, inv(get_val(XB1_RY)) ); // Set RY to the inverse of its current value   }

 

 

 

 

 

 

 

pow raises the given value to the power specified.  What this means is a value will be multiple by itself X amount of times.  For example;

 

int a;   main {       a = pow(5, 3); // a = 125 (5³) or (5 * 5 * 5)   }

 

This function must be used with caution as there is a risk of an integer overflow when using it.  This would occur when the function attempts to return a value greater than 32767 which is the maximum value for a signed 16 bit integer.

 

 

 

 

<expression1> :	any expression which has a value
<expression2> :	any expression which has a value

 

 

 

isqrt returns the square root of a given value.  The square root of a value is the value which when multiplied by itself equals the given value.  For example, the square root of 25 is 5  (5 * 5 = 25). The return value is an integer which means any fractions will be dropped.  As shown below;

 

int a;   main {       a = isqrt(10);  // a = 3.  The square root of 10 is 3.16...                     // GPC supports integer values only so the fraction is dropped.   }
