Mathematical Functions

RTR provides several built-in mathematical functions for performing common calculations.

min

Returns the smallest value among the provided arguments.

min(5, 3, 8);     /* Returns 3 */
min(-1, -5, 0);   /* Returns -5 */

max

Returns the largest value among the provided arguments.

max(5, 3, 8);     /* Returns 8 */
max(-1, -5, 0);   /* Returns 0 */

abs

Returns the absolute value of a number.

abs(-5);          /* Returns 5 */
abs(3.14);        /* Returns 3.14 */

round

Rounds a number to the nearest integer.

round(3.7);       /* Returns 4 */
round(3.2);       /* Returns 3 */
round(-3.7);      /* Returns -4 */

floor

Rounds a number down to the nearest integer.

floor(3.7);       /* Returns 3 */
floor(3.2);       /* Returns 3 */
floor(-3.7);      /* Returns -4 */

ceil

Rounds a number up to the nearest integer.

ceil(3.7);        /* Returns 4 */
ceil(3.2);        /* Returns 4 */
ceil(-3.7);       /* Returns -3 */

sqrt

Returns the square root of a number.

sqrt(16);         /* Returns 4 */
sqrt(2);          /* Returns 1.4142135623730951 */
