类名称:Math
方法名:cosh

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
