| Parameter | Description |
|---|---|
| x | Input value. |
bool True if the value was NaN; false otherwise.
Returns true if the input float is a NaN (not a number) floating point value, false otherwise.
NaN has several representations and may vary across architectures. Use this function to check if you have a NaN.
| Parameter | Description |
|---|---|
| x | Input value. |
bool2 True if the component was NaN; false otherwise.
Returns a bool2 indicating for each component of a float2 whether it is a NaN (not a number) floating point value.
NaN has several representations and may vary across architectures. Use this function to check if you have a NaN.
| Parameter | Description |
|---|---|
| x | Input value. |
bool3 True if the component was NaN; false otherwise.
Returns a bool3 indicating for each component of a float3 whether it is a NaN (not a number) floating point value.
NaN has several representations and may vary across architectures. Use this function to check if you have a NaN.
| Parameter | Description |
|---|---|
| x | Input value. |
bool4 True if the component was NaN; false otherwise.
Returns a bool4 indicating for each component of a float4 whether it is a NaN (not a number) floating point value.
NaN has several representations and may vary across architectures. Use this function to check if you have a NaN.
| Parameter | Description |
|---|---|
| x | Input value. |
