Number formats 00.00

[jpn]

The correct version of QString::arg() was already stated in the second post of this thread.

A hint:

• fieldWidth = 5 (4 digits + decimal point)
• format = 'f'
• precision = 2 (number of digits after the decimal point)
• fillChar = '0'

ok, final one line solution is:

QString str= QString("%1").arg(data, 5, 'f',2, '0');

its working.

[kernel_panic]

whats with QString().sprintf("%.2f");

jacel,

Homework: Reduce all of this to a single line of code.

finally homework done.
QString str= QString("%1").arg(data, 5, 'f',2, '0');

Good, the other solution, as kernel_panic has suggested, is QString().sprintf( "%05.2f", data ).

Remember, be lazy!

Indeed. Read the docs, kids, even if you know them by heart.

I want to know which solution is accepted by maverick_pol...
