commit 3938fcfcfedf451c47cb6307bf270f090956caa0
Author: Bruno Le Floch <bruno at le-floch.fr>

    Use intarray to store 10112 decimals for floating point trigonometry
    
    This doubles the speed of sine (for inputs for which reduction modulo
    2pi was needed).  Now only three times slower than pgfmath, despite
    our thrice bigger precision and lack of "Dimension too large" errors.
