The hexadecimal digits are followed by a binary exponent that consists of
the letter or
p P
digits. The exponent is interpreted as a power of two that is used to scale
the fraction represented by the tokens
The first character that does not fit either form of number will stop the

Error Conditions
The function returns a zero if no conversion can be made and a
strtod
pointer to the invalid string is stored in the object pointed to by
the correct value results in an overflow, a positive or negative (as appropri-
ate) is returned. If the correct value results in an underflow, 0 is

Example
#include <stdlib.h>
char *rem;
double dd;
dd = strtod ("2345.5E4 abc",&rem);
/* dd = 2.3455E+7, rem = "abc" */
dd = strtod ("-0x1.800p+9,123",&rem);
/* dd = -768.0, rem = ",123"
