PHP 3 ways to turn decimals into integers _php tutorial

float Floor (float value) de-rounding Method

Returns the next integer not less than value, rounding out the fractional part of value. The type returned by floor () is still float, because the range of float values is usually larger than the integer.

Copy the Code code as follows: Echo floor (4.3); 4
echo Floor (9.999); 9
float ceil (float value) in one-way rounding

Returns the next integer not less than value, in which value is entered if there is a fractional part. The type returned by Ceil () is still float, because the range of float values is usually larger than the integer.

Copy the Code code as follows:
echo ceil (4.3); 5
echo ceil (9.999); 10
Float round (float val [, int precision]) rounding floating-point numbers

Returns the result of rounding Val based on the specified precision precision (number of digits after decimal point). Precision can also be negative or 0 (the default value).

Copy the Code code as follows:
Echo round (3.4); 3
Echo round (3.5); 4
Echo round (3.6); 4
Echo Round (3.6, 0); 4
Echo Round (1.95583, 2); 1.96
Echo Round (1241757,-3); 1242000
Echo Round (5.045, 2); 5.04
Echo Round (5.055, 2); 5.06
