999,999 is the largest number that can be represented in Pd without
scientific notation. 999,999 in binary is:
1111 0100 0010 0011 1111
But Pd cannot represent this number exactly:
1111 1111 1111 1111 1111 (1,048,575)
but it can represent this number exactly:
0111 1111 1111 1111 1111 (524,287)
Therefore Pd can represent 19-bits of integer accurately.
