NAME

t/native_pbc/number.t - Floating-Point Numbers

SYNOPSIS

        % prove t/native_pbc/number.t

DESCRIPTION

Tests word-size/float-type/endian-ness for different architectures.

These tests usually only work on updated native pbc test files. See tools/dev/mk_native_pbc to create the platform-specific native pbcs.
