float (TP011)

Automatic fix is available.

What it does

Checks for usage of float types.

Why not?

Floating point types are inexact, variable-precision numeric types. Inexact means that some values cannot be converted exactly to the internal format and are stored as approximations, so that storing and retrieving a value might show slight discrepancies.

Comparing two floating-point values for equality might not always work as expected.

When should you?

When approximates are acceptable, no comparison for equality is needed.

Use instead:

1. numeric
2. decimal
