Description

Syntax

fmod(dividend,devisor);

Parameters

• dividend: DOUBLE or FLOAT is supported.

• devisor: DOUBLE or FLOAT is supported.

Note

The data type of devisor needs to be the same as the data type of dividend. Otherwise, CelerData performs implicit conversion to convert the data type.
