Returns the square root of val. Val cannot be a negative value.


GML Code Example


Argument Description
val The number to get the square root of.

Returns: Real


If you multiply a number with itself, you get the square of that number, but sometimes you want to do the reverse and get the square root of a number. So to find what number has been multiplied with itself to get any given positive value we use this function. For example: sqrt(9) will return 3 since 3*3=9.


GML Code Example

num = sqrt(exp);

The above code will set the variable "num" to hold the square root of the value contained in "exp".
