Math.cosh介绍

[英]Returns the closest double approximation of the hyperbolic cosine of the argument. The returned result is within 2.5 ulps (units in the last place) of the real result.

Special cases:

• cosh(+infinity) = +infinity
• cosh(-infinity) = +infinity
• cosh(NaN) = NaN
  [中]返回参数的双曲余弦的最接近的双近似值。返回的结果与实际结果相差2.5 ulps（最后一位为单位）。
  特殊情况：
  *余弦（+无穷大）=+无穷大
  *余弦（-无穷大）=+无穷大
  *cosh（NaN）=NaN
