How to plug in a variable for BCMath?

[Jackson Scott Peebles]

Hello everyone! I could really use some help with BCMath, which I have
just begun a project with. I require it's high-accuracy for a
calculator of mine, but I need to plug in a variable. Now, when I try this:
<?php
echo bcmul('1', '$var', 99); // 1;
?>
It doesn't work! This probably makes sense to you gurus out there, but
I don't know too much about PHP, I'm just starting. How the heck do you
plug in a variable in BCMath? One of you experts, PLEASE help me! The
deadline for the project is coming up soon... and I need the accuracy of
BCMath for a fact! Thanks, and please reply if you know!

That's because you're trying to multiple the string '1' by the string '$var' -
(the string dollar sign, vee, etc.), not the contents of $var as a string.

$var itself needs to be a string. If it's a numeric value, you should still get
automatic conversion to a string. But if not, you can also use:

echo bcmul('1', (string)$var, 99);
