* sqrt($x)
`scss`
@debug sqrt(2); // 1.41421
@debug sqrt(3); // 1.73205
#### Exponential function
* exp($x)
*
*
`scss`
@debug exp(-1); // 0.36788
@debug exp(0); // 1

If argument has deg unit, converted to rad.
`scss`
@debug tan(0.5236); // 0.57735
@debug tan(30deg); // 0.57735
#### Inverse trigonometric functions

* - Arccosine (逆余弦)atan($x)
* - Arctangent (逆正接)atan2($y, $x)
* - Arctangent of the quotient of its arguments (引数の比率での逆正接)
`scss`
@debug atan2(0, 0); // 0
@debug atan2(0, -0.0); // 3.14159
@debug atan2(-0.0, 0); // 0
@debug atan2(-0.0, -0.0); // -3.14159
#### Greatest common divisor and least common multiple
* gcd($a, $b) - Greatest common divisor (最大公約数)lcm($a, $b)
* - Least common multiple (最小公倍数)
`scss`
