eyeglass-math v1.0.1

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-.
