[Feature] Proposal for Comprehensive Mathematical Module in Amber

[Ph0enixKM]

We could start with a mininal version of such library and then we could extend it with other functions. Some of the most important ones could be the following:

Rounding

• [x] ceil(x: Num): Num - rounds up to the nearest integer
• [x] floor(x: Num): Num - rounds down to the nearest
• [x] round(x: Num): Num - rounds to the nearest integer

Absolute and sign

• [x] abs(x: Num): Num - absolute value
• [ ] sign(x: Num): Num - sign function, returns -1, 0, or 1 depending on the sign of x

Min / Max

• [ ] min(a: Num, b: Num): Num
• [ ] max(a: Num, b: Num): Num

Optional: Power, root, exponential, logarithms and trigonometric

These can be easily evaluated using bc with flag -l

• [ ] pow(base: Num, exponent: Num): Num - power function
• [ ] sqrt(x: Num): Num - square root
• [ ] exp(x: Num): Num - exponential function
• [ ] log(x: Num): Num - natural logarithm
• [ ] log10(x: Num): Num - base-10 logarithm
• [ ] sin(x: Num): Num - sine
• [ ] cos(x: Num): Num - cosine
• [ ] tan(x: Num): Num - tangent

(perhaps exp, log, sin/cos, tan are not necessary)

[Ph0enixKM]

You're right @FedericoCeratto. That's not the most important thing right now

As today we have some of them, it is enough?
