Raising to power in PHP
bcmath, exponent, exponentiation, math, php
Solution
The caret is the bit-wise XOR operator in PHP. You need to use `pow()` for integers.
Problem
Well, i need to do some calculations in PHP script. And i have one expression that behaves wrong. ``` echo 10^(-.01); ``` Outputs 10 ``` echo 1 / (10^(.01)); ``` Outputs 0 ``` echo bcpow('10', '-0.01') . '<br/>'; ``` Outputs 1 ``` echo bcdiv('1', bcpow('10', '0.01')); ``` Outputs 1.000.... I'm using `bcscale(100)` for BCMath calculations. Excel and Wolfram Mathematica give answer ~0,977237. Any suggestions?
