Example #1

File: evalf.py Project: smichr/sympy

def evalf_atan(v, prec, options):
    arg = v.args[0]
    xre, xim, reacc, imacc = evalf(arg, prec + 5, options)
    if xre is xim is None:
        return (None,) * 4
    if xim:
        raise NotImplementedError
    return mpf_atan(xre, prec, rnd), None, prec, None

Example #2
