Converts the float type to the int32_t type, and supports multiple rounding modes.

• RINT rounding mode: round half to even

• ROUND rounding mode: round half up

• FLOOR rounding mode: round toward negative infinity

• CEIL rounding mode: round toward positive infinity

• TRUNC rounding mode: round toward zero

• Non-saturation mode:

  • When the input data exceeds the maximum or minimum value of the output type, the result is truncated to the data width of the target format.
  • When the input data is +/-inf, the maximum or minimum value of the output type is returned.
  • When the input data is nan, 0 is returned.

• Saturation mode:

  • When the input data exceeds the maximum or minimum value of the output type, the corresponding maximum or minimum value of the output type is returned.
  • When the input data is +/-inf, the maximum or minimum value of the output type is returned.
  • When the input data is nan, 0 is returned.
