Third attempt of writing a math to JavaScript transpiler

Math.js

Math.js is a math language that transpiles to JavaScript. It allows you to write equations with ease and any prior knowledge.

Examples

Addition

1 + 2 + 3 # 6

We add up 1, 2 and 3 which would result in 6. # is the start of a comment, so it's excluded from any equation.

Multiplication

1.5 * 2 # 3

You can easily multiply numbers, as seen here.

Order of operations

(1 + 2)^3 - 5 * 3 # 12

Math.js follows the standard Order of Operations when calculating an equation.

Functions

Math.js has several built in functions you can use.

• log(x) natural logarithm of x
• logb(x) logarithm of x with base b, example log10(100) # 2
• sqrt(x) take the square root of x
• sin(x) take the sin of x
• cos(x) take the cos of x
• tan(x) take the tan of x
• floor(x) round x down
• ceil(x) round x up
• round(x) round x to the nearest integer
• abs(x) take the absolute value of x
• radians(x) turn x degrees into radians
• degrees(x) turn x radians into degrees

Example usage:

round(2 + sqrt(2^2 / (4 - 2))) # 3

Variables

x = 10 / 2
10 - x # 5

You can easily create variables. These variables can be used in equations, functions and to assign other variables.
