Math and Logic Nodes API

The following boolean and mathematical operations are available which should be self explanatory.

Also note that there is syntactic sugar in place when wiring a graph. Edges have most operators overloaded includes +, -, *, /, **, >, >=, <, <=, ==, !=, so you can have code like csp.const(1) + csp.const(2) work properly. Right hand side values will also automatically be upgraded to csp.const(<value>) if its detected that its not an edge, so something like x = csp.const(1) + 2 will work as well.

Table of Contents

1. Binary logical operators

• csp.not_(ts[bool]) → ts[bool]
• csp.and_(x: [ts[bool]]) → ts[bool]
• csp.or_(x: [ts[bool]]) → ts[bool]

2. Binary mathematical operators

• csp.add(x: ts['T'], y: ts['T']) → ts['T']
• csp.sub(x: ts['T'], y: ts['T']) → ts['T']
• csp.multiply(x: ts['T'], y: ts['T']) → ts['T']
• csp.divide(x: ts['T'], y: ts['T']) → ts[float]
• csp.pow(x: ts['T'], y: ts['T']) → ts['T']
• csp.min/max(x: ts['T'], y: ts['T']) → ts['T']
• gt/ge/lt/le/eq/ne(x: ts['T'], y: ts['T']) → ts[bool]

3. Unary mathematical operators

• ln/log2/log10(x: ts[float]) → ts[float]
• exp/exp2(x: ts[float]) → ts[float]
• sqrt(x: ts[float]) → ts[float]
• abs(x: ts[float]) → ts[float]
• sin/cos/tan/arcsin/arccos/arctan/sinh/cosh/tanh/arcsinh/arccosh/arctanh(x: ts[float]) → ts[float]
• erf(x: ts[float]) → ts[float]
