One more Javascript function

By on July 31st, 2017

This function will format a value expressed as feet (with decimals) into feet and inches.

// Convert feet (decimal) into feet and inches
function toString(value)
{
	var abs = Math.abs(value);
	// Round to nearest 0.1 inch
	var rounded = Math.round(120 * abs) / 120;

	var feet = Math.floor(rounded);
	var inches = 12*(rounded - feet);

	return (value < 0 ? "-" : "")
		+ (feet != 0 ? feet + "'" : "")
		+ (inches.toFixed(1) + '"');
}
