bigdecimal

I've been trying to convert a value of seconds (in a BigDecimal variable) to a string in an editText like "1 hour 22 minutes 33 seconds" or something of the kind. I've tried this: String sequenceCaptureTime = ""; BigDecimal roundThreeCalc = new BigDecimal("0"); BigDecimal hours = new BigDecimal("0"); BigDecimal myremainder = new BigDecimal("0"); BigDecimal minutes = new BigDecimal("0"); BigDecimal seconds = new BigDecimal("0"); BigDecimal var3600 = new BigDecimal("3600"); BigDecimal var60 = new BigDecimal("60"); (I have a roundThreeCalc which is the value in seconds so I try to convert it here

前言： float是浮点数，有时需要做精确的位数处理 正文： 方法1 float f = (float) 34.232323; BigDecimal b = new BigDecimal(f); float f1 = b.setScale(2, BigDecimal.ROUND_HALF_UP).floatValue(); //ROUND_HALF_UP表明四舍五入，ROUND_HALF_DOWN表明五舍六入，2：保留两位小数 方法2 float f = 34.232323; DecimalFormat fmt = new DecimalFormat("##0.00"); String s = fmt.format(f); float f1 = Float.parseFloat(s); 参考博客： Java float保留两位小数_ufeng_新浪博客 http://blog.sina.com.cn/s/blog_77a45ee10101qbuy.html 来源： https://www.cnblogs.com/huashengweilong/p/11332206.html

I'm looking for a C++ class that can do decimal floating point arithmetic. Looking through http://speleotrove.com/decimal/ there are links to all sorts of classes that people have written and not maintained. Digging through the decNumber++ stuff led me to some emails showing that GCC will eventually support this functionality. (Formally known as ISO/IEC TR 24733) I'm looking for something I can use as a drop-in replacement for float or double, something that other people are using in their own projects. Hopefully open source. Thanks! EDIT: I should point out that I'm trying to use this to

Is there a mature library for doing decimal-based math, possibly arbitrary-precision, in JavaScript? Edit: I want this information for a reference page on floating-point-related problems and alternatives to use when binary floating-point is inappropriate: http://floating-point-gui.de/ Pointy There's been a "port" of the Java BigDecimal class (I think it's here: http://freshmeat.net/projects/js_bigdecimal/ ) for a long time. I looked at it a long time ago and it seemed kind-of cumbersome and huge, but (if that's the one I'm thinking of) it's been used as part of some cryptography tools so there

I have a collection of BigDecimals (in this example, a LinkedList ) that I would like to add together. Is it possible to use streams for this? I noticed the Stream class has several methods Stream::mapToInt Stream::mapToDouble Stream::mapToLong Each of which has a convenient sum() method. But, as we know, float and double arithmetic is almost always a bad idea. So, is there a convenient way to sum up BigDecimals? This is the code I have so far. public static void main(String[] args) { LinkedList<BigDecimal> values = new LinkedList<>(); values.add(BigDecimal.valueOf(.1)); values.add(BigDecimal

金额的计算BigDecimal类 double d = 9.84; double d2 = 1.22; //注意需要使用BigDecimal(String val)构造方法 BigDecimal bigDecimal = new BigDecimal(Double.toString(d)); BigDecimal bigDecimal2 = new BigDecimal(Double.toString(d2)); //加法 BigDecimal bigDecimalAdd = bigDecimal.add(bigDecimal2); double add = bigDecimalAdd.doubleValue(); //减法 BigDecimal bigDecimalSubtract = bigDecimal.subtract(bigDecimal2); double subtract = bigDecimalSubtract.doubleValue(); //乘法 BigDecimal bigDecimalMultiply = bigDecimal.multiply(bigDecimal2); double multiply = bigDecimalMultiply.doubleValue(); //除法 int scale = 2;//保留2位小数 BigDecimal
