Module rsvg::float_eq_cairo

Utilities to compare floating-point numbers.

Constants

• CAIRO_FIXED_FRAC_BITS 🔒
• CAIRO_FIXED_MAX 🔒
• CAIRO_FIXED_MAX_DOUBLE
  The largest representable fixed-point number, as a double. This is a bit over 8 million.
• CAIRO_FIXED_MIN 🔒
• CAIRO_FIXED_MIN_DOUBLE
  The most negative representable fixed-point number, as a double. This is a bit less than -8 million.
• CAIRO_FIXED_ONE_DOUBLE 🔒
  The double that corresponds to (the number one in fixed-point representation)
• CAIRO_MAGIC_NUMBER_FIXED 🔒

Traits

• ApproxEqCairo
  Checks whether two floating-point numbers are approximately equal, considering Cairo’s limitations on numeric representation.
• FixedEqCairo
  Implements a method to check whether two f64 numbers would have the same fixed-point representation in Cairo.

Functions

• cairo_fixed_from_double 🔒
