Examples with RubyInteger org.jruby.RubyInteger used on opensource projects

Example 1 with RubyInteger

use of org.jruby.RubyInteger in project jruby-openssl by jruby.

the class BN method exp.

    // exponent even approaching Integer.MAX_VALUE would be silly big, and
    // the value would take a very, very long time to calculate.)
    // we'll check for values < 0 (illegal) while we're at it
    int exp = -1;
