PHP offers a variety of functions to perform mathematical operations on numbers.<\/p>\n\n\n\n

PHP pi()<\/code> Function<\/h2>\n\n\n\n

The pi()<\/code> function returns the value of Pi:<\/p>\n\n\n\n

echo(pi());<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
PHP min()<\/code> and max()<\/code> Functions<\/h2>\n\n\n\n
The min()<\/code> and max()<\/code> functions can be used to find the smallest or largest value in a set of arguments:<\/p>\n\n\n\n
echo(min(10, 150, 30, 20, -8, -200)); \/\/ Outputs: -200\necho(max(10, 150, 30, 20, -8, -200)); \/\/ Outputs: 150<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
PHP abs()<\/code> Function<\/h2>\n\n\n\n
The abs()<\/code> function returns the absolute (positive) value of a number:<\/p>\n\n\n\n
echo(abs(-9.7)); \/\/ Outputs: 9.7<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
PHP sqrt()<\/code> Function<\/h2>\n\n\n\n
The sqrt()<\/code> function returns the square root of a number:<\/p>\n\n\n\n
echo(sqrt(81)); \/\/ Outputs: 9<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
PHP round()<\/code> Function<\/h2>\n\n\n\n
The round()<\/code> function rounds a floating-point number to the nearest integer:<\/p>\n\n\n\n
echo(round(0.70)); \/\/ Outputs: 1\necho(round(0.49)); \/\/ Outputs: 0<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Random Numbers<\/h2>\n\n\n\n
The rand()<\/code> function generates a random number:<\/p>\n\n\n\n
echo(rand());<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
To generate a random number within a specific range, you can include optional minimum and maximum parameters. For example, to get a random integer between 50 and 150:<\/p>\n\n\n\n
echo(rand(50, 150));<\/pre><\/div>\n\n\n\n
