PHP floor() Function – Truncating Float to Integer
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.
The PHP floor() function returns the greatest integer value less than or equal to a given float, effectively discarding the fractional part.
Signature: float floor(float $value)
Parameter: $value – the number to be truncated.
Return value: A float representing the nearest integer not greater than $value ; the type remains float because its range exceeds that of an integer.
