Thank you, I have tried to re-enable Scanf floating point support in project settings. And successfully used sscanf to get the float double.

What's kind of error? If you just want to show the float or double type data. You may transfer it to integer. EX: 3.141*1000=3141 int x1=3141/1000 int x2=3141%1000 printf("%d.%03d",x1,x2);

Have you enabled printf floating point support in the project settings? SES will then set the appropriate linker flag.

So that's the display problems. Because your double type value is correct. The compiler option. You may find out the SES C manual.

Display problems?....

I am not sure. Because my code result is like this.

The value is correct!

in gcc SES C

remeber to add on compiler flag

LDFLAGS += -u _scanf_float

if you use sscanf(); function

char *pEnd;

Val_double=strtod(testdou,&pEnd);
