ftoa

int ftoa( float f, char * buf );

Description

Converts a float number to a character string.

The character string only displays the mantissa up to 9 digits, no decimal points, and a minus sign if f is negative. The function returns the exponent (of 10) that should be used to compensate for the string: ftoa(1.0,buf) yields buf="100000000" and returns -8.

Parameters

f

Float number to convert.

buf

Converted string. The string is no longer than 10 characters long.

Return value

The exponent of the number.
