cgroup_parse_float

Name:group_parse_float - parse a floating number*@input: input string*@dec_shift: number of decimal digits to shift*@v: output* Parse a decimal floating point number in @input and store the result in*@v with decimal point right shifted @dec_shift times

Proto:int cgroup_parse_float(const char *input, unsigned dec_shift, s64 *v)

Type:int

Parameter:

Type	Parameter	Name
const char *	input
unsigned	dec_shift
s64 *	v

6206

frac = 0

6207

fstart = 0 , fend = 0

6209

If Not sscanf - Unformat a buffer into a list of arguments*@buf: input buffer*@fmt: formatting of buffer*@...: resulting arguments Then Return -EINVAL

6211

If frac < 0 Then Return -EINVAL

6214

flen = If fend > fstart Then fend - fstart Else 0

6215

If flen < dec_shift Then frac *= power_of_ten(dec_shift - flen)

6217

Else frac = Same as above but for u64 dividends. divisor must be a 32-bit* number.(frac, power_of_ten(flen - dec_shift))

6220

v = whole * power_of_ten(dec_shift) + frac

6221

Return 0
