Functions
| abs (x) | Returns the absolute value of x. |
| acos (x) | Returns the arc cosine of x (in radians). |
| asin (x) | Returns the arc sine of x (in radians). |
| atan (x) | Returns the arc tangent of x (in radians). |
| atan2 (y, x) | Returns the arc tangent of y/x (in radians), but uses the signs
of both parameters to find the quadrant of the result. |

quotient towards zero. |
| frexp (x) | Returns m and e such that x = m2^e, e is an integer and the
absolute value of m is in the range [0.5, 1) (or zero when x is zero). |
| ldexp (m, e) | Returns m2^e (e should be an integer). |

produce equal sequences of numbers. |
