The absolute value of a complex number is the length ! 15: of the hypotenuse of a right triangle whose sides are given by ! 16: the real part r and the imaginary part i. The result is the ! 17: square root of the sum of the squares of the parts. ! 18: ! 19: ***** Example ***** ! 20: ! 21: For an example of this function, see the entry for acos. ! 22: ! 23: ***** See Also ***** ! 24: ! 25: hypot(), mathematics library ! 26: ! 27: ! 28: ! 29: ! 30: ! 31: ! 32: ! 33: ! 34: ! 35: ! 36: ! 37: ! 38: ! 39: ! 40: ! 41: ! 42: ! 43: ! 44: ! 45: ! 46: ! 47: ! 48: ! 49: ! 50: ! 51: ! 52: ! 53: ! 54: ! 55: ! 56: ! 57: ! 58: ! 59: ! 60: ! 61: ! 62: ! 63: ! 64: COHERENT Lexicon Page 1 ! 65: ! 66:
