Eyeglass Math
This eyeglass plugin exposes Javascript's Math API to Sass.
To use it:
$ npm install --save eyeglass-math

Then in your Sass file(s):
@import "math";

API

The following constants are available when you import the math module.
  • $PI - The ratio of a circle's circumference to its diameter.
  • $TAU - Because Pi is wrong.
  • $E - The natural base (2.718…).

The following functions are available when you import the math module.

math/numeric

  • sign($number) - Returns the sign of the x, indicating whether
$number is positive (1), negative (-1) or zero (0).

math/exponentiation

  • cbrt($number) - Returns the cube root of a number.
  • exp($number) - Returns E^x, where x is the argument, and E
is Euler's constant (2.718…), the base of the natural logarithm.
  • log($number) - Returns the natural logarithm of a number.
  • log10($number) - Returns the base 10 logarithm of a number.
  • log2($number) - Returns the base 2 logarithm of a number.
  • pow(base, exponent) - Returns $base to the $exponent power.
  • sqrt($number) - Returns the positive square root of a number.

math/trigonometry

  • acos($number) - Returns the arccosine of a number.
  • asin($number) - Returns the arcsine of a number.
  • atan($number) - Returns the arctangent of a number.
  • cos($number) - Returns the cosine of a number.
  • hypot($numbers...) - Returns the square root of the sum of
squares of its arguments.
  • sin($number) - Returns the sine of a number.
  • tan($number) - Returns the tangent of a number.

math/hyperbolic

  • acosh($number) - Returns the hyperbolic arccosine of a number.
  • asinh($number) - Returns the hyperbolic arcsine of a number.
  • atanh($number) - Returns the hyperbolic arctangent of a number.
  • cosh($number) - Returns the hyperbolic cosine of a number.
  • sinh($number) - Returns the hyperbolic sine of a number.
  • tanh($number) - Returns the hyperbolic tangent of a number.

Note: The functions above are available as globals with the prefix math-.
