/************************************
* GetFloatFromString
* extract a floating point number from a string.
* NOTE: the only punctuation in the string is the decimal separator that
* separates the left-hand and right-hand parts of the numbers. This is because
* users cannot enter thousands-delimiting characters in numbers fields.
************************************/
float GetFloatFromString ( Char * str ) {
Char part1 [12], part2 [12];
float fval1, fval2, fresult;
Int16 j, k;
fval1 = 0.0; part1 [0] = '\0';
fval2 = 0.0; part2 [0] = '\0';
// strip off LHS of number
j = 0;
while (( str [ j ] != '\0' ) &&
( str [ j ] != Dsep )) {
part1 [ j ] = str [ j ]; // get LHS
j++;
}
part1 [ j ] = '\0'; // done, terminate it
// strip off RHS of number
k = 0;
if ( str [ j ] == Dsep ) j++;
while ( str [ j ] != '\0' ) {
part2 [ k ] = str [ j ]; // get RHS
j++; k++;
}
part2 [ k ] = '\0'; // done, terminate it
// convert the two parts to floating point #s
fval1 = ( float ) StrAToI ( part1 );
fval2 = ( float ) StrAToI ( part2 );
// convert RHS to proper fraction
for ( j = 1; j <= StrLen ( part2 ); j++ ) {
fval2 = fval2 / 10.0;
fval2 = fval2;
}
// combine the results
fresult = fval1 + fval2;
return ( fresult );
}
