 | I need to convert a double to a string. I've been using sprintf on a
Pocket PC, but I don't know what to use for Palm OS. I need to be able
to set the precision too. Please help! Thanks.

| Found that function somewhere on google:
void doubleToStr (char* str, double flpNumber, UInt8 numFractDigits)
{
double flpIP, zeros, round, remainder;
UInt8 i, strLen;
char sign = ' ';
if (flpNumber < 0.0)
{
flpNumber = -flpNumber;
sign = '-';
}
zeros = pow (10, numFractDigits); // get the rounding constant
round = 0.5 / zeros;
flpNumber = modf (flpNumber + round, &flpIP); // get integer and
fractional parts
str[0] = sign;
StrIToA (&str[1], (UInt16)flpIP);
strLen = StrLen (str); // put in the decimal point and terminate the
string
str[strLen] = '.';
str[numFractDigits + strLen + 1] = '\0';
flpNumber = flpNumber * zeros; // fractional part
for (i = numFractDigits + strLen; i > strLen; i--) // convert the integer
part
{
remainder = fmod (flpNumber, 10);
str[i] = remainder + 0x30;
flpNumber /= 10;
}
}
Hope that helps, Alex
