Constructor & Destructor Documentation

Precision()

ssgx::decimal_t::Precision::Precision	(	RoundType	round_type,
		int	scale )

Constructor.

Parameters

[in]	round_type	The rounding type, one of RoundType value.
[in]	scale	> 0, Keep significant digits up to a certain decimal place = 0, The result will be kept as an integer < 0, Keep significant digits up to a certain integer place

Note

Parameter scale must less than SSGX_MAX_PREC(99), otherwise an exception will occur.

@par Examples
@codeotherwise an exception will occur
     BigDecimal a("123.456");
     BigDecimal b("2.2");
     BigDecimal result;
     Precision prec1(ROUND_HALF_UP, 2);
     Precision prec2(ROUND_HALF_UP, 0);
     Precision prec3(ROUND_HALF_UP, -2);
 
     // Use the default precision
     result = a.Multiply(b);         // 271.6032
 
     // Round to two decimal places
     result = a.Multiply(b, prec1);  // 271.60
 
     // Value kept as an integer
     result = a.Multiply(b, prec2);  // 272
 
     // Significant digits up to the hundreds place
     result = a.Multiply(b, prec3);  // 300
