Description

实现一个算法（或更多）来计算Gamma （$ \ Gamma $）函数（仅在实际字段中）。 Gamma功能可以定义为：

$ \ Gamma（x）= \ displaystyle \ int_0 ^ \ infty t ^ {x-1} e ^ { - t} dt $

Instructions

Tests

tests:
  - text: <code>gamma</code>应该是一个功能。
    testString: assert(typeof gamma=='function')
  - text: '<code>gamma(&quot;+tests[0]+&quot;)</code>应该返回一个数字。'
    testString: assert(typeof gamma(.1)=='number')
  - text: '<code>gamma(&quot;+tests[0]+&quot;)</code>应该返回<code>&quot;+results[0]+&quot;</code> 。'
    testString: assert.equal(round(gamma(.1)), round(9.513507698668736))
  - text: '<code>gamma(&quot;+tests[1]+&quot;)</code>应该返回<code>&quot;+results[1]+&quot;</code> 。'
    testString: assert.equal(round(gamma(.2)), round(4.590843711998803))
  - text: '<code>gamma(&quot;+tests[2]+&quot;)</code>应该返回<code>&quot;+results[2]+&quot;</code> 。'
    testString: assert.equal(round(gamma(.3)), round(2.9915689876875904))
  - text: '<code>gamma(&quot;+tests[3]+&quot;)</code>应该返回<code>&quot;+results[3]+&quot;</code> 。'
    testString: assert.equal(round(gamma(.4)), round(2.218159543757687))
  - text: '<code>gamma(&quot;+tests[4]+&quot;)</code>应返回<code>&quot;+results[4]+&quot;</code> 。'
    testString: assert.equal(round(gamma(.5)), round(1.7724538509055159))

Challenge Seed
