intmax — Return the largest value of an integer class.
intmax returns the largest representable value for an integer class. With no class name, RunMat follows MATLAB's int32 default.
Syntax
value = intmax()
value = intmax(classname)
value = intmax(like=prototype)Inputs
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
classname | StringScalar | Yes | — | Numeric class name. |
like | StringScalar | Yes | — | Like keyword. |
prototype | LikePrototype | Yes | — | Integer prototype whose class and complexity are copied. |
Returns
| Name | Type | Description |
|---|---|---|
value | Any | Limit value. |
Errors
| Identifier | When | Message |
|---|---|---|
RunMat:numericLimits:InvalidClass | The requested class is not supported by the limit query. | numeric limit: unsupported class |
RunMat:numericLimits:InvalidSyntax | The arguments do not match a documented class-name or like-prototype form. | numeric limit: invalid syntax |
How intmax works
- Supports int8, int16, int32, int64, uint8, uint16, uint32, and uint64 class names.
Does RunMat run intmax on the GPU?
No GPU kernels are launched.
GPU memory and residency
The result is host-resident.
Example
Default integer maximum
intmaxExpected output:
ans = int32(2147483647)Using intmax with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how intmax changes the result.
Run a small intmax example, explain the result, then change one input and compare the output.
