PostgreSQL Error 22P01: Floating Point Exception
PostgreSQL error code 22P01 is raised when a floating-point operation produces an exceptional result that cannot be represented as a valid number. This typically occurs during division by zero on float types, operations involving NaN (Not a Number), or arithmetic that yields Infinity. It is most commonly encountered in analytics, financial calculations, and data pipelines processing external or sensor data.

1. Division by Zero on Float Types
Unlike integer division (which raises 22012), dividing a float by zero triggers a floating-point exception. This is especially common in ratio and rate calculations where the denominator can become zero at runtime.
