Calculates the arctangent (in radians) of the quotient of two numbers.
$atan2(number1,number2)
number1 | a number, or an expression that evaluates to a number |
number2 | a number, or an expression that evaluates to a number |
Number, with the same number of decimal places as number1.
Number1 is divided by number2 before the arctangent is calculated.
The value returned by $atan2 has the same number of decimal places as number1.
$atan2(1.000,2)
The above command is equivalent to $atan(0.500) and returns the value 0.464.
