Allow more functions to be used in blueprint parameterization

[Iterniam]

From what I could find, we can currently use the following functions in the formulas/math expressions field of a value parameter:

• a * b
• a / b
• a + b
• a - b
• a ^ b
• min(a, b)
• max(a, b)
• abs(a)

I would like to compute the automated insertion limit as a parameter, the formula for which can be found here viewtopic.php?p=309796#p309796
This requires* ceil() as part of the calculation.
More generally, it would also be nice to have the following formulas available:

• ceil(a, b)
• floor(a, b)
• clamp(a, b, c)
• mod(a, b) or a % b
• div(a, b) or a // b (integer division, python style - is the counterpart to mod)
• and(a, b)
• or(a, b)
• xor(a, b)
• a << b
• a >> b
• a == b (these comparisons return 1 or 0)
• a != b
• a < b
• a <= b
• a > b
• a >= b

I don't expect all of these to be implemented, but parity with arithmetic combinators would make a lot of sense. Ceil/Floor would also make great additions.

*ceil can be implemented in terms of modulo, so parity with arithmetic combinators would suffice, although it's not elegant

Adding to this request in hopes of getting "clamp" available. If I recall correctly, "clamp" is already implemented in the scope of a noise expression, but it's not in the base MathExpression.

I was experimenting with a parameterized BP for a bot-based mall assembler, and I hoped to do something like:

Code: Select all

inner_bit => some formula using e.g. p0_i1 and p0_t, for example
clamp(inner_bit, 1, 25)

Note: I split it into two lines and omitted the math for readability purposes. In the actual parameter, they'd be one line.

The goals are that I never want a request=0 bug, and I never want to request more than a hard-coded upper bound at a time (even if that slows it down).

I can and did solve that using min+max, but it's not nearly as clear, especially when inner_bit is expanded:

Code: Select all

max(min(inner_bit, 25), 1)

Floor/Ceil or even just Mod are severely needed in MathExpression for complicated blueprint parameterisation.
