Math extension for CEL — mirrors ext.Math() from cel-go.

Provides numeric functions under the math.* namespace.

Usage

env = Celixir.Environment.new() |> Celixir.Ext.Math.register()
Celixir.eval!("math.sqrt(16.0)", env)  # => 4.0
Celixir.eval!("math.ceil(1.2)", env)   # => 2.0

Functions

• math.ceil(double) — ceiling
• math.floor(double) — floor
• math.round(double) — round (ties away from zero)
• math.trunc(double) — truncate fractional part
• math.abs(int|uint|double) — absolute value
• math.sign(int|uint|double) — -1, 0, or 1
• math.sqrt(int|uint|double) — square root (NaN for negative)
• math.isNaN(double) — true if NaN
• math.isInf(double) — true if ±Inf
• math.isFinite(double) — true if neither NaN nor Inf
• math.bitAnd(int, int) / math.bitAnd(uint, uint)
• math.bitOr(int, int) / math.bitOr(uint, uint)
• math.bitXor(int, int) / math.bitXor(uint, uint)
• math.bitNot(int) / math.bitNot(uint)
• math.bitShiftLeft(int|uint, int)
• math.bitShiftRight(int|uint, int)
• math.greatest(arg, ...) / math.greatest(list) — variadic max (built-in only)
• math.least(arg, ...) / math.least(list) — variadic min (built-in only)
