Value Providers and You

A constant value provider can be given in the form of a number.

However usually, a value provider takes the field type to define which kind of value provider to use (and thus what fields to provide), can be one of the following:

1. constant: A constant number as its singular field value, equivalent to inlining a number as the value provider.
2. invert: Makes the value provider of its field invert negative if positive, and positive if negative.
3. function: Performs a mathematical operation from the field operation and its fields, with the following operations:

• add, sub, mul, div: Standard mathematical operations, you know what these are. Takes additional value providers left and right, representing which side of the sign they are on.
• mod: Returns the remainder of dividing left by right. Takes additional value providers left and right, representing which side of the sign they are on.
• pow: Returns the result of raising left to the power of right. Takes additional value providers left and right, representing which side of the sign they are on.
• sqrt: Returns the square root of operand. Takes value provider operand.
• sin, asin, cos, acos, tan, atan: Returns the result of running their respective trigonometric on operand. Takes value provider operand.
• min: Returns the smaller between left and right. Takes additional value providers left and right, representing which side of the sign they are on.
• max: Returns the larger between left and right. Takes additional value providers left and right, representing which side of the sign they are on.
• round, floor, ceil: Returns the result of the rounding operation on operand. Takes value provider operand.

4. variable: Stand-in for the variable present in context, optionally takes in var as a variable name, defaulting to "input" if not present.
