Struct write_fonts::util::FloatComparator

pub struct FloatComparator { /* private fields */ }

Compare two floats for equality using relative and absolute tolerances.

This is useful when porting from Python where math.isclose is common.

• PEP425

Implementations

impl FloatComparator

pub fn new(rel_tol: f64, abs_tol: f64) -> Self

Create a new FloatComparator with the specified relative and absolute tolerances.

pub fn isclose(self, a: f64, b: f64) -> bool

Return true if a and b are close according to the specified tolerances.
