85 页 共 85 页数学函数Abs说明返回参数的绝对值。语法Numeric Abs(Numeric Number)参数Number 需要计算其绝对值的实数。备注返回参数的绝对值，参数绝对值是参数去掉正负号后的数值。示例Abs (2) = 2；Abs (-2) = 2；Abs (0) = 0；Abs (-5.3) = 5.3；Abs (10.43) = 10.43。Acos说明返回参数的反余弦值。语法Numeric Acos(Numeric Number)参数Number 角度的余弦值，必须介于 -11 之间。如果要用度表示反余弦值，需将结果再乘以 180/PI()。 备注返回数字的反余弦值。反余弦值为一个角度，而该角度的余弦值即为该函数的参数。返回的角度值以弧度表示，范围是0到Pi。示例Acos (-0.5) = 2.094395(2* Pi /3 弧度)；Acos (-0.5)*180/ Pi () = 120°(度)。Acosh说明返回参数的反双曲余弦值。语法Numeric Acosh(Numeric Number)参数Number 大于等于 1 的实数。备注返回参数的反双曲余弦值。参数 Number 必须大于或等于 1。反双曲余弦值的双曲余弦即为该函数的参数，因此 Acosh (Cosh(Number) 等于 Number。示例Acosh (1) = 0；Acosh (10) = 2.993223。Asin说明返回参数的反正弦值。语法Numeric Asin(Numeric Number)参数Number 角度的正弦值，必须介于 -11 之间。备注返回参数的反正弦值。反正弦值为一个角度，该角度的正弦值即等于此函数的参数。返回角度的单位为弧度，且范围在 - Pi /2 到 Pi /2 之间。示例Asin (-0.5) = -0.5236 ( - Pi /6 弧度)；Asin (-0.5)*180/ Pi () = -30 (度)。Asinh说明返回参数的反双曲正弦值。语法Numeric Asinh(Numeric Number)参数Number 任意实数。备注返回参数的反双曲正弦值，反双曲正弦值的双曲正弦即等于此函数的参数值，因此，Asinh (Sinh( Number) 的值等于 Number。示例Asinh (-2.5) = -1.64723；Asinh (10) = 2.998223。Atan说明返回参数的反正切值。语法Numeric Atan(Numeric Number)参数Number 角度的正切值。备注返回参数的反正切值。反正切值为角度，其正切值即等于参数值。返回的角度值将以弧度表示，范围为 -pi/2 到 pi/2。如果要用度表示反正切值，需将结果再乘以 180/( )。示例Atan (1) = 0.785398(Pi /4 弧度)；Atan (1)*180/() = 45(度)。Atan2说明返回给定的 X 及 Y 坐标值的反正切值。语法Numeric Atan2(Numeric X_num,Numeric Y_num)参数X_num 点的 X 坐标。Y_num 点的 Y 坐标。 备注返回给定的 X 及 Y 坐标值的反正切值。反正切的角度值等于 X 轴与通过原点和给定坐标点（X_num, Y_num）的直线之间的夹角。结果以弧度表示并介于 - Pi到 Pi之间（不包括 - Pi）。结果为正表示从 X 轴逆时针旋转的角度，结果为负表示从X 轴顺时针旋转的角度。Atan2 (a, b) 等于 ATAN(b/a)，除非 Atan2值为零。如果 X_num 和 Y_num 都为零，Atan2返回无效值。如果要用度表示反正切值，需将结果再乘以 180/ Pi()。 示例Atan2 (1, 1) = 0.785398 (pi/4弧度)；Atan2 (-1, -1) = -2.35619 (-3* Pi /4 弧度)；Atan2 (-1, -1)*180/ Pi () = -135 (度)。 Atanh说明返回参数的反双曲正切值。语法Numeric Atanh(Numeric Number)参数Number -11 之间的任意实数。备注返回参数的反双曲正切值，参数必须在 -11 之间（除去 -1 和 1）。反双曲正切值的双曲正切即为该函数的参数值，因此 Atanh (Tanh(Number) 等于 Number。示例Atanh (0.76159416) = 1 （近似值）；Atanh (-0.1) = -0.10034。Ceiling说明将参数 Number 沿绝对值增大的方向，舍入为最接近的整数或基数Significance的最小倍数。语法Numeric Ceiling(Numeric Number,Numeric Significance)参数Number 待舍入的数值。Significance 基数。备注将参数 Number 沿绝对值增大的方向，舍入为最接近的整数或基数Significance的最小倍数。例如，如果您不愿意使用像"分"这样的零钱，而所要购买的商品价格为 $4.42，可以用公式 = Ceiling (4.42,0.1) 将价格舍入为以"角"表示。如果参数为非数值型，Ceiling返回无效值。无论数字符号如何，都按远离 0 点方向舍入。如果数字已经为 Significance 的倍数，则不进行舍入。如果 Number 和 Significance 符号不同，Ceiling返回无效值。示例Ceiling (2.5, 1) = 3；Ceiling (-2.5, -2) = -4；Ceiling (-2.5, 2) = 无效值；Ceiling (1.5, 0.1) = 1.5；Ceiling (0.234, 0.01) = 0.24。 Combin说明计算从给定数目的对象集合中提取若干对象的组合数。语法Integer Combin (Numeric Number,Numeric Number_chosen)参数Number 对象总的数量。Number_chosen 每一组合中对象的数量。备注数字参数截尾取整。如果任一参数为非数值型，Combin返回无效值。如果 number < 0、number_chosen < 0 或 number < number_chosen，Combin返回无效值。对象组合是对象整体的任意子集，且不论其内部顺序。组合与排列不同，排列数与对象顺序有关。假设从 8 名候选者中选出 2 人组成一队，求所有可能的组合数：Combin (8, 2 ) 等于 28 种编队方案。 示例Combin(8, 2) = 28。 Cos说明返回给定角度的余弦值。语法Numeric Cos(Numeric Number)参数Number 为需要求余弦的角度，以弧度表示。如果参数的单位是度，则可以乘以Pi ()/180 将其转换为弧度。备注返回给定角度的余弦值。示例Cos (1.047) = 0.500171；Cos (60*Pi()/180) = 0.5，即 60 度的余弦值。Cosh说明返回参数的双曲余弦值。语法Numeric Cosh(Numeric Number)参数Number 表示要为其找到双曲线余弦的任意实数。 备注返回参数的双曲余弦值。示例Cosh (4) = 27.30823；Cosh (Exp(1) = 7.610125，式中 Exp(1) 等于 e，即自然对数的底数。Ctan说明返回给定角度的余切值。语法Numeric Ctan(Numeric Number)参数Number 需要计算其反余切值的实数。备注返回给定角度的余切值。示例Ctan (0.785) = 1.00080；Ctan (45* Pi ()/180) = 1。Even说明返回沿绝对值增大方向取整后最接近的偶数。语法Integer Even(Numeric Number)参数Number 所要取整的数值。备注返回沿绝对值增大方向取整后最接近的偶数。使用该函数可以处理那些成对出现的对象。如果 Number 为非数值参数，则 Even返回无效值。不论 Number 的正负号如何，函数都向远离零的方向舍入，如果 Number 恰好是偶数，则无需进行任何舍入处理。 示例Even (1.5) = 2；Even (3) = 4；Even (2) = 2；Even (-1) = -2。 Exp说明返回e的Number次幂。语法Numeric Exp(Numeric Number)参数Number 为底数e的指数。备注返回e的Number次幂。常数 e 等于 2.71828182845904，是自然对数的底数。如果要计算以其他常数为底的幂，请用指数操作符（）。Exp函数是计算自然对数的 Ln 函数的反函数。示例Exp (1) = 2.718282(e 的近似值)；Exp (2) = e2 或 7.389056；Exp (Ln(3) = 3。 Fact说明返回数的阶乘。语法Integer Fact(Numeric Number)参数Number 要计算其阶乘的非负数。如果输入的Number不是整数，则截尾取整。备注返回数的阶乘。
