#### Description

The →∡d command turns a scalar into an angle measured in degrees / minutes / seconds.

The angle is entered / displayed as a real number in the format DD.MMSSxxx… where:

• DD expresses the number of degrees;
• MM expresses the number of minutes of arc and ranges from 00 to 59;
• SS expresses the number of seconds of arc and ranges from 00 to 59;
• xxx… expresses the remaining fraction of seconds of arc.

When a scalar is converted to an angle in degrees / minutes / seconds no check is performed to ensure that the digits at MM and SS positions range from 00 to 59. However addition of 0 (or multiplication by 1) will return a properly normalized angle.

#### Compatibility

→∡d is specific to newRPL and has no direct equivalent in userRPL.

#### Usage

To see how normalization works, let's enter an “incorrect” angle; for example $30° 75^{\prime} 10^{\prime\prime}$:

Input

2:
1:                                30.751
…………………………………………………………………………………………………………
→∡d                                     

Output

4:
3:
2:
1:                              ∡30.751d
…………………………………………………………………………………………………………


To trigger normalization of $30° 75^{\prime} 10^{\prime\prime}$ it's sufficient to multiply it by 1:

Input

4:
3:
2:
1:                              ∡30.751d
…………………………………………………………………………………………………………
1 *                                     

Output

4:
3:
2:
1:                             ∡31.151.d
…………………………………………………………………………………………………………


The normalized angle is $31° 15^{\prime} 10^{\prime\prime}$.
