Calculates the hyperbolic sine of number.
Syntax
double|decimal sinh(<number>)Parameters
number: required. A value of the DOUBLE or DECIMAL type. If the input value is of the STRING or BIGINT type, the value is implicitly converted into a value of the DOUBLE type before calculation.
Return value
A value of the DOUBLE or DECIMAL type is returned. The return value varies based on the following rules:
- If number is of the DOUBLE or DECIMAL type, a value of the same type is returned.
- If number is of the STRING or BIGINT type, a value of the DOUBLE type is returned.
- If the value of number is null, null is returned.
Sample data
This section provides sample source data and examples for you to understand how to use the functions. In this topic, a table named mf_math_fun_t is created and data is inserted into the table. Sample statements:
create table if not exists mf_math_fun_t(
int_data int,
bigint_data bigint,
double_data double,
decimal_data decimal,
float_data float,
string_data string
);
insert into mf_math_fun_t values
(null, -10, 0.525, 0.525BD, cast(0.525 as float), '10'),
(-20, null, -0.1, -0.1BD, cast(-0.1 as float), '-10'),
(0, -1, null, 20.45BD, cast(-1 as float), '30'),
(-40, 4, 0.89, null, cast(0.89 as float), '-30'),
(5, -50, -1, -1BD, null, '50'),
(-60, 6, 1.5, 1.5BD, cast(1.5 as float), '-50'),
(-1, -70, -7.5, -7.5BD, cast(-7.5 as float),null ),
(-80, 1, -10.2, -10.2BD, cast(-10.2 as float), '-1' ),
(9, -90, 2.58, 2.58BD, cast(2.58 as float), '0'),
(-100, 10, -5.8, -5.8BD, cast(-5.8 as float), '-90');Query data from the mf_math_fun_t table. Sample statement:
select * from mf_math_fun_t;

Calculate the hyperbolic sine of values in a column based on the sample data. Sample statement:
select sinh(bigint_data) as bigint_new, sinh(double_data) as double_new, sinh(decimal_data) as decimal_new, sinh(string_data) as string_new from mf_math_fun_t;The following result is returned:
