LCD float out problem

[Berkl]

Hello guys!

Problem with LCD indication:

If I need out to LCD float = 0.001 by the follow function:

void Write_LCD(unsigned char row, unsigned char col,float tmp_var)
{

char tmp_string[14];

FloatToStr(tmp_var,tmp_string);
Lcd8_Custom_Out(row,col,tmp_string);
}
then I will see on LCD: "1e-3"

But I need to see "0.001" !!
How I can do that, please?

Thank you for your answer
Have a nice day!

Hello,

if you are using

Code: Select all

FloatToStr(tmp_var,tmp_string);

Converts a floating point number to a string. The output string is left justified and null terminated after the last digit.
example:

Code: Select all

float ff3 = 0.000001234;
.
.
.
FloatToStr(ff3, txt);  // txt is "1.234e-6"

It's not recommended to use this function if you want the output like "0.001".
Suggestion is that you use library sprintf!
The function returns the number of characters actually written to destination string.
For more informations, look for sprintf in our help file.

If you have any additional questions, feel free to contact me.

Best regards,
