Inacurate precision truncating.

Zhi Chen over 24 years ago

Hi folk,
I have

u16 wTemp = 0;
fsingle fTemp = 17.5123;

wTemp = (u16)fTemp;

Somehow, the wTemp is 17. Technically, the wTemp should be 18, do anybody know what do I have to do for the compiler in order to generate more precise data conversion???

Thanks!

No, integer casts on floats truncate so 17 is correct. Look up floor() and ceil() in your manual, they will help do what you want.
