ATAN Arc tangent: tan-1x. Output range is from -90° to 90°, 2π/2 to π/2, or -100 to 100 grads. Inputs and outputs depend on the current angle format. Also accepts complex numbers. ATAN(value) Example ATAN(1) returns 45 (Degrees mode). Square. Also accepts complex numbers. value2 Example 182 returns 324 Square root. Also accepts complex numbers. value Example 324 returns 18 Negation. Also accepts complex numbers. -value Example -(1,2) returns (-1,-2) Power (x raised to y). Also accepts complex numbers. value^power Example 2^8 returns 256 ABS Absolute value. For a complex number, this is x2 + y2 . ABS(value) ABS((x,y)) Example ABS(-1) returns 1 ABS((1,2)) returns 2.2360679775 Using mathematical functions 13-5
