Subject: Use << for raising 2 to power instead of ^
X-Git-Tag: lyx-2.4.0dev-acb2ca7b~1061
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=8f3c95f7570f84effc4601e88f13ff48c6084f0c;hp=104fdcc9be40df19d50cddad7f8ae9ab63bbf5f7;p=features.git

Use << for raising 2 to power instead of ^

The ^ is interpretted as bitwise XOR, so 2^(20) evaluated to 22.

Thanks to Riki for the << trick. This way, we do not have to use
pow() and include the <cmath> header for this one expression.
