decimal128

decimal128(X, scale)

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

scale is an integer in [0,38] that determines the number of digits to the right of the decimal point.

Convert the input values into DECIMAL128.

a=decimal128(142, 2)
a
// output
142.00

b=decimal128(1\7, 6)
b
// output
0.142857

a+b
// output
142.142857

a*b
// output
20.28569400

decimal128("3.1415926535", 4)
// output
3.1416

// All elements of a DECIMAL vector must be of the same type and scale
d1=[1.23$DECIMAL128(4), 3$DECIMAL128(4), 3.14$DECIMAL128(4)];
// output
[1.2300,3.0000,3.1400]
typestr(d1)
// output
FAST DECIMAL128 VECTOR

// If the elements are of different scales, a tuple is created
d2=[1.23$DECIMAL128(4), 3$DECIMAL128(4), 3.14$DECIMAL128(3)];
// output
(1.2300,3.0000,3.140)
typestr(d2)
// output
ANY VECTOR
