Syntax

pow(base, exponent);

Parameter	Description
Base	Number can be integer or float
Exponent	Number can be integer or float

It returns the value of base raised to the power of exponent.

Pow() function is used to find multiplication of first argument itself second parameter times.

For example ₅2 =25. In case of pow function 5 is first argument (base) and 2 is second argument (exponent) of pow function.

Note: The pow function is capable of handled the negative power and exponent also.

<?php

echo "10 to power 3=";

echo pow( 10, 3 );

?>

In above example, first argument (base) is 10 and second argument (exponent) is 3 so that result will be 1000.

<?php

echo "10 to power -3=";

echo pow( 10, -3 );

echo "10 to power 0.5=";

echo pow( 10, 0.5);

?>

In first pow function, first argument (base) is 10 and second argument (exponent) is -3 so that result will be 0.001 not 1000.
