decimal64

Syntax

decimal64(X, scale)

Arguments

X is a scalar/vector of Integral, Floating, or STRING type.

scale is an integer in [0,18] that determines the number of digits to the right of the decimal point.

Details

Convert the input values into DECIMAL64.

Examples

a=decimal64(142, 2)
a
// output
142.00

b=decimal64(1\7, 6)
b
// output
0.142857

a+b
// output
142.142857

a*b
// output
20.28569400

decimal64("3.1415926535", 4)
// output
3.1415

// the elements of a DECIMAL vector must be of the same decimal type and scale
d1=[1.23$DECIMAL64(4), 3$DECIMAL64(4), 3.14$DECIMAL64(4)];
// output
[1.2300,3.0000,3.1400]
typestr(d1)
// output
FAST DECIMAL64 VECTOR

d2=[1.23$DECIMAL64(4), 3$DECIMAL64(4), 3.14$DECIMAL64(3)];
// output
(1.2300,3.0000,3.140)
typestr(d2)
// output
ANY VECTOR

Note: When converting data of STRING/SYMBOL type into DECIMAL, there has been a modification in the way the decimal part exceeding the scale is handled since version 2.00.10.

Before version 2.00.10, the decimal part is truncated;
Starting from version 2.00.10, the decimal part is rounded.

symbol(["1.341", "4.5677"])$DECIMAL64(2)
//before version 2.00.10, the output is:
[1.34,4.56]
//starting from version 2.00.10, the output turns to:
[1.34,4.57]
