Assuming your formula is correct, checked longhand in Python 3.8.0 using the math library:

Code:

0.5607915159336736
>>> math.exp((0.5-0.3581)*0.5)/(1.0+math.exp((0.5-0.3581)*0.5))
0.5177300630065548
>>> math.exp((1.0-0.005268)*25)/(1.0+math.exp((1.0-0.005268)*25))
0.9999999999841571
>>> _

So your rounded values seem OK.
Again this assumes that your formula is correct.

NAME

       frexpd64(), frexpd128(), frexpd32() - extract mantissa and exponent from decimal floating-point numbers

SYNOPSIS

DESCRIPTION

       The  function  breaks  a  decimal floating-point number into a normalized decimal fraction f and an integral power of 10.  It returns f and
       stores the integer exponent of 10 in the object pointed to by exp.  The fraction f is a with magnitude in the interval [0.1,  1)  or  zero,
       and value equals f times 10 raised to the power *exp.

       is a version of it takes a first argument and returns a result.

RETURN VALUE

       If value is zero, returns value and stores zero in the object pointed to by exp.

       If value is NaN, returns NaN, and the value of *exp is unspecified.

       If value returns value, and the value of *exp is unspecified.

       These functions raise no exceptions.

ERRORS

       No errors are defined.
