new 96bbf205 Added integer conversion in toBoolean functions (#1199)
96bbf205 is described below
commit 96bbf205d7c63153c82eb190be94d0b784d0a6df
Author: Wendel de Lana <[email protected]>

Added integer conversion in toBoolean functions (#1199)
Implemented integer conversion to boolean in both toBoolean and
toBooleanList functions. Also made corresponding changes to regression
tests and broke long lines to adhere to the 79-column line length limit
in the toBooleanList function.
