### 7.5 Arithmetic Functions

Function: `void` mpf_add `(mpf_t rop, const mpf_t op1, const mpf_t op2)` ¶
Function: `void` mpf_add_ui `(mpf_t rop, const mpf_t op1, unsigned long int op2)` ¶

  Set rop to op1 + op2.

Function: `void` mpf_sub `(mpf_t rop, const mpf_t op1, const mpf_t op2)` ¶
Function: `void` mpf_ui_sub `(mpf_t rop, unsigned long int op1, const mpf_t op2)` ¶
Function: `void` mpf_sub_ui `(mpf_t rop, const mpf_t op1, unsigned long int op2)` ¶

  Set rop to op1 − op2.

Function: `void` mpf_mul `(mpf_t rop, const mpf_t op1, const mpf_t op2)` ¶
Function: `void` mpf_mul_ui `(mpf_t rop, const mpf_t op1, unsigned long int op2)` ¶

  Set rop to op1 times op2.

Division is undefined if the divisor is zero, and passing a zero divisor to the divide functions will make these functions intentionally divide by zero. This lets the user handle arithmetic exceptions in these functions in the same manner as other arithmetic exceptions.

Function: `void` mpf_div `(mpf_t rop, const mpf_t op1, const mpf_t op2)` ¶
Function: `void` mpf_ui_div `(mpf_t rop, unsigned long int op1, const mpf_t op2)` ¶
Function: `void` mpf_div_ui `(mpf_t rop, const mpf_t op1, unsigned long int op2)` ¶

  Set rop to op1/op2.

Function: `void` mpf_sqrt `(mpf_t rop, const mpf_t op)` ¶
Function: `void` mpf_sqrt_ui `(mpf_t rop, unsigned long int op)` ¶

  Set rop to the square root of op.

Function: `void` mpf_pow_ui `(mpf_t rop, const mpf_t op1, unsigned long int op2)` ¶

  Set rop to op1 raised to the power op2.

Function: `void` mpf_neg `(mpf_t rop, const mpf_t op)` ¶

  Set rop to −op.

Function: `void` mpf_abs `(mpf_t rop, const mpf_t op)` ¶

  Set rop to the absolute value of op.

Function: `void` mpf_mul_2exp `(mpf_t rop, const mpf_t op1, mp_bitcnt_t op2)` ¶

  Set rop to op1 times 2 raised to op2.

Function: `void` mpf_div_2exp `(mpf_t rop, const mpf_t op1, mp_bitcnt_t op2)` ¶

  Set rop to op1 divided by 2 raised to op2.
