This article explains PHP floating-point precision issues, demonstrates common arithmetic errors, and shows how to use the bcmath extension and various rounding functions such as floor, ceil, round, and number_format to achieve accurate numeric calculations in backend development.
The article explains PHP's floor() function, describing its signature, parameter, return type, and provides example code showing how it truncates floating‑point numbers to the nearest lower integer, with sample outputs for positive and negative values.
This article explains PHP’s ceil() function, describing how it rounds a floating‑point number up to the smallest integer not less than the given value, details its parameter and return type, and provides example code with expected outputs.
JavaScript’s unexpected result for 0.1 + 0.2 versus the exact 0.3 + 0.4 arises because numbers are stored in IEEE‑754 double‑precision binary, where limited mantissa bits require exponent alignment and rounding (ties‑to‑even), causing small representation errors that appear as 0.30000000000000004.
