ST STM32WB Series Programming Manual

The STM32 Cortex-M4 instruction set PM0214
154/262 PM0214 Rev 9
3.10.4 VCVT, VCVTR between floating-point and integer
Converts a value in a register from floating-point to a 32-bit integer.
Syntax
VCVT{R}{cond}.Tm.F32 Sd, Sm
VCVT{cond}.F32.Tm Sd, Sm
Where:
• ‘R’ .
If R is specified, the operation uses the rounding mode specified by the FPSCR.
If R is omitted. the operation uses the Round towards Zero rounding mode.
• ‘cond’ is an optional condition code, see Conditional execution on page 65.
• ‘Tm’ is the data type for the operand. It must be one of:
S32 signed 32-bit value.
U32 unsigned 32-bit value.
• ‘Sd, Sm’ are the destination register and the operand register.
Operation
These instructions:
1. Either
• Converts a value in a register from floating-point value to a 32-bit integer.
• Converts from a 32-bit integer to floating-point value.
2. Places the result in a second register.
The floating-point to integer operation normally uses the Round towards Zero rounding
mode, but can optionally use the rounding mode specified by the FPSCR.
The integer to floating-point operation uses the rounding mode specified by the FPSCR.
Restrictions
There are no restrictions.
Condition flags
These instructions do not change the flags.
