    Math.asin, recommended that implementations use the approximation
    algorithms for IEEE 754 arithmetic contained in fdlibm
es5id: 15.8.2.3_A6
description: >
    Checking if Math.asin is approximately equals to its mathematical
    values on the set of 64 argument values; all the sample values is
    calculated with LibC
includes:
    - math_precision.js
    - math_isequal.js
