character and float?

Question

char A;
float B=1.2;
how can i make char A take the value of 1.2?

i tried A=char(B) in my program....cant work

i also tried float(A)=B.... still wrong...

Answer 1

there is know way to assign 1.2 to a single char. if you want a sequence of char's to hold a string containing the characters "1.2" you could:



char A[10];

sprintf(A,"%4.1f",B);

Answer 2

Casting, i.e. A = (char) B should work. Or you could convert it using ftoa. Why would you want to do this in the first place?

Answer 3

very simple.. lol

use this c library function.



Answer: gcvt(B,2,A)



char * gcvt ( double value, int num, char * buffer );



Parameters.

value

Floating point value to be converted to a string.

num

Number of digits to generate.

buffer

Memory block where to store the resulting string.

Answer 4

You can't. A character can only hold integer values from -128 to 127 (or from 0 to 255 if it's unsigned).

Answer 5

You should probably say what language you're using...

Answer 6

It will be helpfull if you tell what lang it is?

Answer 7

If C, try sprintf()
